3 main reasons:
- The cert and key that we store in this object are not always used for TLS.
- The package name "provider" was a little too generic.
- dynamiccert.Provider reads more go-ish than provider.DynamicCertProvider.

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
- Add flag parsing and help messages for root command,
`exchange-credential` subcommand, and new `get-kubeconfig` subcommand
- The new `get-kubeconfig` subcommand is a work in progress in this
commit
- Also add here.Doc() and here.Docf() to enable nice heredocs in
our code
So I looked into other TokenReview webhook implementations, and most
of them just use the json stdlib package to unmarshal/marshal
TokenReview payloads. I'd say let's follow that pattern, even though
it leads to extra fields in the JSON payload (these are not harmful).

- Also correct the webhook url setting in prepare-for-integration-tests.sh
- Change the bcrypt count to 10, because 16 is way too slow on old laptops

- For now, build the test-webhook binary in the same container image as
the pinniped-server binary, to make it easier to distribute
- Also fix lots of bugs from the first draft of the test-webhook's
`/authenticate` implementation from the previous commit
- Add a detailed README for the new deploy-test-webhook directory
The webhook still needs to be updated to auto generate its
certificates.
We decided not to give this webhook its own go module for now since
this webhook only pulled in one more dependency, and it is a
dependency that we will most likely need in the future.

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.

- We want to follow the <noun>Request convention.
- The actual operation does not login a user, but it does retrieve a
credential with which they can login.
- This commit includes changes to all LoginRequest-related symbols and
constants to try to update their names to follow the new
CredentialRequest type.

I suppose we could solve this other ways, but this utility was
only used in one place right now, so it is easiest to copy it over.

- Also, don't repeat `spec.Parallel()` because, according to the docs
for the spec package, "options are inherited by subgroups and subspecs"
- Two tests are left pending to be filled in on the next commit
- `Before` gives a nice place to call `require.New(t)` to make the assertion lines more terse
- Just delete the keys for testing when env vars are missing
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.

The type signatures of these methods make them easy to mix up. `require.Error()` asserts that there is any non-nil error -- the last parameter is an optional human-readable message to log when the assertion fails. `require.EqualError()` asserts that there is a non-nil error _and_ that when you call `err.Error()`, the string matches the expected value. It also takes an additional optional parameter to specify the log message.

Again, no idea why but this word has two commonly accepted spelling and Go code seems to very consistently use the one with one "l".

This is a somewhat more basic way to get access to the certificate and private key we need to issue short lived certificates.
The host path, tolerations, and node selector here should work on any kubeadm-derived cluster including TKG-S and Kind.

- 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.
