In the upstream dynamiccertificates package, we rely on two pieces
of code:
1. DynamicServingCertificateController.newTLSContent which calls
- clientCA.CurrentCABundleContent
- servingCert.CurrentCertKeyContent
2. unionCAContent.VerifyOptions which calls
- unionCAContent.CurrentCABundleContent
This results in calls to our tlsServingCertDynamicCertProvider and
impersonationSigningCertProvider. If we Unset these providers, we
subtly break these consumers. At best this results in test slowness
and flakes while we wait for reconcile loops to converge. At worst,
it results in actual errors during runtime. For example, we
previously would Unset the impersonationSigningCertProvider on any
sync loop error (even a transient one caused by a network blip or
a conflict between writes from different replicas of the concierge).
This would cause us to transiently fail to issue new certificates
from the token credential require API. It would also cause us to
transiently fail to authenticate previously issued client certs
(which results in occasional Unauthorized errors in CI).

At a high level, it switches us to a distroless base container image, but that also includes several related bits:
- Add a writable /tmp but make the rest of our filesystems read-only at runtime.
- Condense our main server binaries into a single pinniped-server binary. This saves a bunch of space in
the image due to duplicated library code. The correct behavior is dispatched based on `os.Args[0]`, and
the `pinniped-server` binary is symlinked to `pinniped-concierge` and `pinniped-supervisor`.
- Strip debug symbols from our binaries. These aren't really useful in a distroless image anyway and all the
normal stuff you'd expect to work, such as stack traces, still does.
- Add a separate `pinniped-concierge-kube-cert-agent` binary with "sleep" and "print" functionality instead of
using builtin /bin/sleep and /bin/cat for the kube-cert-agent. This is split from the main server binary
because the loading/init time of the main server binary was too large for the tiny resource footprint we
established in our kube-cert-agent PodSpec. Using a separate binary eliminates this issue and the extra
binary adds only around 1.5MiB of image size.
- Switch the kube-cert-agent code to use a JSON `{"tls.crt": "<b64 cert>", "tls.key": "<b64 key>"}` format.
This is more robust to unexpected input formatting than the old code, which simply concatenated the files
with some extra newlines and split on whitespace.
- Update integration tests that made now-invalid assumptions about the `pinniped-server` image.

This may be a temporary fix. It switches the manual auth code prompt to use `promptForValue()` instead of `promptForSecret()`. The `promptForSecret()` function no longer supports cancellation (the v0.9.2 behavior) and the method of cancelling in `promptForValue()` is now based on running the blocking read in a background goroutine, which is allowed to block forever or leak (which is not important for our CLI use case).
This means that the authorization code is now visible in the user's terminal, but this is really not a big deal because of PKCE and the limited lifetime of an auth code.
The main goroutine now correctly waits for the "manual prompt" goroutine to clean up, which now includes printing the extra newline that would normally have been entered by the user in the manual flow.
The text of the manual login prompt is updated to be more concise and less scary (don't use the word "fail").

This test is asynchronously waiting for the controller to do something, and in some of our test environments it will take a bit longer than we'd previously allowed.

this will hopefully fix some flakes where aws provisioned a host for the
load balancer but the tests weren't able to resolve it.

It seems like page.ClearCookies() only clears cookies for the current
domain, so there doesn't seem to be a function to clear all browser
cookies. Instead, we'll just start a whole new browser each test.
They start fast enough that it shouldn't be a problem.
Our actual CLI code behaved correctly, but this test made some invalid assumptions about the "upstream" IDP we're testing. It assumed that the upstream didn't support `response_mode=form_post`, but Okta does. This means that when we end up on the localhost callback page, there are no URL query parameters.
Adjusting this regex makes the test pass as expected.

Using the same fake TTY trick we used to test LDAP login, this new subtest runs through the "manual"/"jump box" login flow. It runs the login with a `--skip-listen` flag set, causing the CLI to skip opening the localhost listener. We can then wait for the login URL to be printed, visit it with the browser and log in, and finally simulate "manually" copying the auth code from the browser and entering it into the waiting CLI prompt.

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.
