This isn't strictly necessary because we currently always have the concierge endpoint and CA as CLI flags, but it doesn't hurt and it's better to err on the side of _not_ reusing a cache entry.

Before this change, the "context", "cluster", and "user" fields in generated kubeconfig YAML were always hardcoded to "pinniped". This could be confusing if you generated many kubeconfigs for different clusters.
After this change, the fields will be copied from their names in the original kubeconfig, suffixed with "-pinniped". This suffix can be overridden by setting the new `--generated-name-suffix` CLI flag.
The goal of this change is that you can distinguish between kubeconfigs generated for different clusters, as well as being able to distinguish between the Pinniped and original (admin) kubeconfigs for a cluster.

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.

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 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.
