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.

Also added more unit tests for the load balancer.

If someone has already set impersonation headers in their request, then
we should fail loudly so the client knows that its existing impersonation

- Watch a configmap to read the configuration of the impersonation
proxy and reconcile it.
- Implements "auto" mode by querying the API for control plane nodes.
- WIP: does not create a load balancer or proper TLS certificates yet.
Those will come in future commits.

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.

This allows us to keep all of our resources in the pinniped category
while not having kubectl return errors for calls such as:
kubectl get pinniped -A
Signed-off-by: Monis Khan <mok@vmware.com>
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.

- I realized that the hardcoded fakekubeapi 404 not found response was invalid,
so we were getting a default error message. I fixed it so the tests follow a
higher fidelity code path.
- I caved and added a test for making sure the request body was always closed,
and believe it or not, we were double closing a body. I don't *think* this will
matter in production, since client-go will pass us ioutil.NopReader()'s, but
at least we know now.

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 reverts commit 4a28d1f800.
This commit was originally made to fix a bug that caused TokenCredentialRequest
to become slow when the server was idle for an extended period of time. This was
to address a Kubernetes issue that was fixed in 1.19.5 and onward. We are now
running with Kubernetes 1.20, so we should be able to pick up this fix.
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

- Only sync on add/update of secrets in the same namespace which
have the "storage.pinniped.dev/garbage-collect-after" annotation, and
also during a full resync of the informer whenever secrets in the
same namespace with that annotation exist.
- Ignore deleted secrets to avoid having this controller trigger itself
unnecessarily when it deletes a secret. This controller is never
interested in deleted secrets, since its only job is to delete
existing secrets.
- No change to the self-imposed rate limit logic. That still applies
because secrets with this annotation will be created and updated
regularly while the system is running (not just during rare system
configuration steps).
We stared at this very carefully and we don't think there are any structural changes. Maybe something small happened to get the RNG off by one?

possible to try to get the code back to stable so we can release.

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.

From RFC2616 (https://www.w3.org/Protocols/rfc2616/rfc2616-sec4.html#sec4.2):

This was correct before, but this simplifes a bit and shaves off a few bytes from the response.
Signed-off-by: Matt Moyer <moyerm@vmware.com>
The bug itself has to do with when headers are streamed to the client. Once a wrapped handler has sent any bytes to the `http.ResponseWriter`, the value of the map returned from `w.Header()` no longer matters for the response. The fix is fairly trivial, which is to add those response headers before invoking the wrapped handler.
The existing unit test didn't catch this due to limitations in `httptest.NewRecorder()`. It is now replaced with a new test that runs a full HTTP test server, which catches the previous bug.
