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 change updates our clients to always set an owner ref when:
1. The operation is a create
2. The object does not already have an owner ref set

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.

This refactors the `UpstreamOIDCIdentityProviderI` interface and its implementations to pass ID token claims through a `*oidctypes.Token` return parameter rather than as a third return parameter.

This is just a more convenient copy of these values which are already stored inside the ID token. This will save us from having to pass them around seprately or re-parse them later.

We missed this in the original interface specification, but the `grant_type=authorization_code` requires it, per RFC6749 (https://tools.ietf.org/html/rfc6749#section-4.1.3).

This allows the token exchange request to be performed with the correct TLS configuration.
We go to a bit of extra work to make sure the `http.Client` object is cached between reconcile operations so that connection pooling works as expected.

- Also continue renaming things related to the concierge app
- Enhance the uninstall test to also test uninstalling the supervisor
and local-user-authenticator apps
Right now in the YTT templates we assume that the agent pods are gonna use
the same image as the main Pinniped deployment, so we can use the same logic
for the image pull secrets.

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.

These configuration knobs are much more human-understandable than the
previous percentage-based threshold flag.
We now allow users to set the lifetime of the serving cert via a ConfigMap.
Previously this was hardcoded to 1 year.

- Seems like the next step is to allow override of the CA bundle; I didn't
do that here for simplicity of the commit, but seems like it is the right
thing to do in the future.
This is kind of a subtle bug, but we were using the unversioned Kubernetes type package here, where we should have been using the v1beta1 version. They have the same fields, but they serialize to JSON differently.

- 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.
