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.
This adds two new flags to "pinniped get kubeconfig": --skip-validation and --timeout.
By default, at the end of the kubeconfig generation process, we validate that we can reach the configured cluster. In the future this might also validate that the TokenCredentialRequest API is running, but for not it just verifies that the DNS name resolves, and the TLS connection is available on the given port.
If there is an error during this check, we block and retry for up to 10 minutes. This duration can be changed with --timeout an the entire process can be skipped with --skip-validation.

This is more than an automatic merge. It also includes a rewrite of the CredentialIssuer API impersonation proxy fields using the new structure, and updates to the CLI to account for that new API.

This flag selects a CredentialIssuer to use when detecting what mode the Concierge is in on a cluster. If not specified, the command will look for a single CredentialIssuer. If there are multiple, then the flag is required.

The login commands now expect either `--concierge-mode ImpersonationProxy` or `--concierge-mode TokenCredentialRequestAPI` (the default).
This is partly a style choice, but I also think it helps in case we need to add a third major mode of operation at some point.
I also cleaned up some other minor style items in the help text.

Also:
- Changed base64 encoding of impersonator bearer tokens to use
`base64.StdEncoding` to make it easier for users to manually
create a token using the unix `base64` command
- Test the headers which are and are not passed through to the Kube API
by the impersonator more carefully in the unit tests
- More WIP on concierge_impersonation_proxy_test.go

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.

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/)

- Adds two new subcommands: `pinniped get kubeconfig` and `pinniped login static`
- Adds concierge support to `pinniped login oidc`.
- Adds back wrapper commands for the now deprecated `pinniped get-kubeconfig` and `pinniped exchange-credential` commands. These now wrap `pinniped get kubeconfig` and `pinniped login static` respectively.

This default matches the static client we have defined in the supervisor, which will be the correct value in most cases.

We decided that we don't really need these in every case, since we'll be returning username and groups in a custom claim.

This will allow it to be imported by Go code outside of our repository, which was something we have planned for since this code was written.

This was hidden behind a `pinniped alpha` hidden subcommand, but we're comfortable enough with the CLI flag interface now to promote it.

Based on the spec, it seems like it's required that OAuth2 servers which do not support PKCE should just ignore the parameters, so this should always work.

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
