- Also some light prefactoring in login.go to make room for LDAP-style
login, which is not implemented yet in this commit. TODOs are added.
- And fix a test pollution problem in login_oidc_test.go where it was
using a real on-disk CLI cache file, so the tests were polluted by
the contents of that file and would sometimes cause each other to
fail.
We have some nice normalization code in this package to remove expired or otherwise malformed cache entries, but we weren't calling it in the appropriate place.
Added calls to normalize the cache data structure before and after each transaction, and added test cases to ensure that it's being called.

We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.
Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.
All controller unit tests were accidentally using a timeout context
for the informers, instead of a cancel context which stays alive until
each test is completely finished. There is no reason to risk
unpredictable behavior of a timeout being reached during an individual
test, even though with the previous 3 second timeout it could only be
reached on a machine which is running orders of magnitude slower than
usual, since each test usually runs in about 100-300 ms. Unfortunately,
sometimes our CI workers might get that slow.
This sparked a review of other usages of timeout contexts in other
tests, and all of them were increased to a minimum value of 1 minute,
under the rule of thumb that our tests will be more reliable on slow
machines if they "pass fast and fail slow".
This change adds a new virtual aggregated API that can be used by
any user to echo back who they are currently authenticated as. This
has general utility to end users and can be used in tests to
validate if authentication was successful.

This is a partial revert of 288d9c999e. For some reason it didn't occur to me
that we could do it this way earlier. Whoops.
This also contains a middleware update: mutation funcs can return an error now
and short-circuit the rest of the request/response flow. The idea here is that
if someone is configuring their kubeclient to use middleware, they are agreeing
to a narrow-er client contract by doing so (e.g., their TokenCredentialRequest's
must have an Spec.Authenticator.APIGroup set).
I also updated some internal/groupsuffix tests to be more realistic.

When the Pinniped server has been installed with the `api_group_suffix`
option, for example using `mysuffix.com`, then clients who would like to
submit a `TokenCredentialRequest` to the server should set the
`Spec.Authenticator.APIGroup` field as `authentication.concierge.mysuffix.com`.
This makes more sense from the client's point of view than using the
default `authentication.concierge.pinniped.dev` because
`authentication.concierge.mysuffix.com` is the name of the API group
that they can observe their cluster and `authentication.concierge.pinniped.dev`
does not exist as an API group on their cluster.
This commit includes both the client and server-side changes to make
this work, as well as integration test updates.

Yes, this is a huge commit.
The middleware allows you to customize the API groups of all of the
*.pinniped.dev API groups.
Some notes about other small things in this commit:
- We removed the internal/client package in favor of pkg/conciergeclient. The
two packages do basically the same thing. I don't think we use the former
anymore.
- We re-enabled cluster-scoped owner assertions in the integration tests.
This code was added in internal/ownerref. See a0546942 for when this
assertion was removed.
- Note: the middlware code is in charge of restoring the GV of a request object,
so we should never need to write mutations that do that.
- We updated the supervisor secret generation to no longer manually set an owner
reference to the deployment since the middleware code now does this. I think we
still need some way to make an initial event for the secret generator
controller, which involves knowing the namespace and the name of the generated
secret, so I still wired the deployment through. We could use a namespace/name
tuple here, but I was lazy.

This is a bit more clear. We're changing this now because it is a non-backwards-compatible change that we can make now since none of this RFC8693 token exchange stuff has been released yet.
There is also a small typo fix in some flag usages (s/RF8693/RFC8693/)

- The overall timeout for logins is increased to 90 minutes.
- The timeout for token refresh is increased from 30 seconds to 60 seconds to be a bit more tolerant of extremely slow networks.
- A new, matching timeout of 60 seconds has been added for the OIDC discovery, auth code exchange, and RFC8693 token exchange operations.
The new code uses the `http.Client.Timeout` field rather than managing contexts on individual requests. This is easier because the OIDC package stores a context at creation time and tries to use it later when performing key refresh operations.

Before this, we weren't properly parsing the `Content-Type` header. This breaks in integration with the Supervisor since it sends an extra encoding parameter like `application/json;charset=UTF-8`.
This change switches to properly parsing with the `mime.ParseMediaType` function, and adds test cases to match the supervisor behavior.

I think this should be more correct. In the server we're authenticating the request primarily via the `subject_token` parameter anyway, and Fosite needs the `client_id` to be set.

New resource naming conventions:
- Do not repeat the Kind in the name,
e.g. do not call it foo-cluster-role-binding, just call it foo
- Names will generally start with a prefix to identify our component,
so when a user lists all objects of that kind, they can tell to which
component it is related,
e.g. `kubectl get configmaps` would list one named "pinniped-config"
- It should be possible for an operator to make the word "pinniped"
mostly disappear if they choose, by specifying the app_name in
values.yaml, to the extent that is practical (but not from APIService
names because those are hardcoded in golang)
- Each role/clusterrole and its corresponding binding have the same name
- Pinniped resource names that must be known by the server golang code
are passed to the code at run time via ConfigMap, rather than
hardcoded in the golang code. This also allows them to be prepended
with the app_name from values.yaml while creating the ConfigMap.
- Since the CLI `get-kubeconfig` command cannot guess the name of the
CredentialIssuerConfig resource in advance anymore, it lists all
CredentialIssuerConfig in the app's namespace and returns an error
if there is not exactly one found, and then uses that one regardless
of its name
So that operators won't look at the lifetime of the CA cert and be
like, "wtf, why does the serving cert have the lifetime that I
specified, but its CA cert is valid for 100 years".

This should simplify our build/test setup quite a bit, since it means we have only a single module (at the top level) with all hand-written code. I'll leave `module.sh` alone for now but we may be able to simplify that a bit more.

- Users may want to consume pkg/config to generate configuration files.
- This also involved putting config-related utilities in the config
package for ease of consumption.
- We did not add in versioning into the Config type for now...this is
something we will likely do in the future, but it is not deemed
necessary this early in the project.
- The config file format tries to follow the patterns of Kube. One such
example of this is requiring the use of base64-encoded CA bundle PEM
bytes instead of a file path. This also slightly simplifies the config
file handling because we don't have to 1) read in a file or 2) deal
with the error case of the file not being there.
- The webhook code from k8s.io/apiserver is really exactly what we want
here. If this dependency gets too burdensome, we can always drop it,
but the pros outweigh the cons at the moment.
- Writing out a kubeconfig to disk to configure the webhook is a little
janky, but hopefully this won't hurt performance too much in the year
2020.
- Also bonus: call the right *Serve*() function when starting our
servers.
