For some reason our headless Chrome test setup behaves slightly differently on Linux and macOS hosts. On Linux, the emoji characters are not recognized as valid text, so they are URL encoded. This change updates the test to cope with both cases correctly.

This adds a new login flow that allows manually pasting the authorization code instead of receiving a browser-based callback.

This is a new pacakge internal/oidc/provider/formposthtml containing a number of static files embedded using the relatively recent Go "//go:embed" functionality introduced in Go 1.16 (https://blog.golang.org/go1.16).
The Javascript and CSS files are minifiied and injected to make a single self-contained HTML response. There is a special Content-Security-Policy helper to calculate hash-based script-src and style-src rules.
This new code is covered by a new integration test that exercises the JS/HTML functionality in a real browser outside of the rest of the Supervisor.

This test did not tolerate this connection failing, which can happen for any number of flaky networking-related reasons. This change moves the connection setup into an "eventually" retry loop so it's allowed to fail temporarily as long as it eventually connects.

TestSimultaneousLDAPRequestsOnSingleProvider proved to be unreliable
on AKS due to some kind of kubectl port-forward issue, so only
run the LDAP client's integration tests on Kind. They are testing
the integration between the client code and the OpenLDAP test server,
not testing anything about Kubernetes, so running only on Kind should
give us sufficient test coverage.
This fixes some rare test flakes caused by a data race inherent in the way we use `assert.Eventually()` with extra variables for followup assertions. This function is tricky to use correctly because it runs the passed function in a separate goroutine, and you have no guarantee that any shared variables are in a coherent state when the `assert.Eventually()` call returns. Even if you add manual mutexes, it's tricky to get the semantics right. This has been a recurring pain point and the cause of several test flakes.
This change introduces a new `library.RequireEventually()` that works by internally constructing a per-loop `*require.Assertions` and running everything on a single goroutine (using `wait.PollImmediate()`). This makes it very easy to write eventual assertions.

This change updates the impersonator to always authorize every
request instead of relying on the Kuberentes API server to perform
the check on the impersonated request. This protects us from
scenarios where we fail to correctly impersonate the user due to
some bug in our proxy logic. We still rely completely on the API
server to perform admission checks on the impersonated requests.

This change updates the impersonation proxy code to run as a
distinct service account that only has permission to impersonate
identities. Thus any future vulnerability that causes the
impersonation headers to be dropped will fail closed instead of
escalating to the concierge's default service account which has
significantly more permissions.

When anonymous authentication is disabled, the impersonation proxy
will no longer authenticate anonymous requests other than calls to
the token credential request API (this API is used to retrieve
credentials and thus must be accessed anonymously).

There was nothing to guarantee that _all_ Supervisor pods would be ready to handle this request. We saw a rare test flake where the LDAPIdentityProvider was marked as ready but one of the Supervisor pods didn't have it loaded yet and returned an HTTP 422 error (`Unprocessable Entity: No upstream providers are configured`).

The `require.Eventually()` function runs the body of the check in a separate goroutine, so it's not safe to use other `require` assertions as we did here. Our `library.RequireEventuallyWithoutError()` function does not spawn a goroutine, so it's safer to use here.

The LastUpdateTime is no longer updated on every resync. It only changes if the underlying status has changed, so that it effectively shows when the transition happened.
This change happened in ab750f48aa, but we missed this test. It only fails when it has been more than ten minutes since the CredentialIssuer transitioned into a healthy state, but that can happen in our long-running CI environments.

This test felt overly complex and some of the cleanup logic wasn't 100% correct (it didn't clean up in all cases).
The new code is essentially the same flow but hopefully easier to read.

We see that occasionally kubectl returns 11 lines (probably related to https://github.com/kubernetes/kubernetes/issues/72628).
This test doesn't need to be so picky, so now it allows +/- one line from the expected count.

We had this one test that mutated the CredentialIssuer, which could cause the impersonation proxy to blip on one or both of the running concierge pods. This would sometimes break other concurrently running tests.
Instead, this bit of code is split into a separate non-concurrent test.

This is to allow the use of binary LDAP entry attributes as the UID.
For example, a user might like to configure AD’s objectGUID or maybe
objectSid attributes as the UID attribute.
This negatively impacts the readability of the UID when it did not come
from a binary value, but we're considering this an okay trade-off to
keep things simple for now. In the future, we may offer more
customizable encoding options for binary attributes.
These UIDs are currently only used in the downstream OIDC `sub` claim.
They do not effect the user's identity on the Kubernetes cluster,
which is only based on their mapped username and group memberships from
the upstream identity provider. We are not currently supporting any
special encoding for those username and group name LDAP attributes, so
their values in the LDAP entry must be ASCII or UTF-8 in order for them
to be interpreted correctly.
This test setup should tolerate when the TokenCredentialRequest API isn't quite ready to authenticate the user or issue a cert.
