I found that there are some situations with `response_mode=form_post` where Chrome will open additional speculative TCP connections. These connections will be idle so they block server shutdown until the (previously 5s) timeout. Lowering this to 500ms should be safe and makes any added latency at login much less noticeable.
More information about Chrome's TCP-level behavior here: https://bugs.chromium.org/p/chromium/issues/detail?id=116982#c5

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.

This flag is (for now) meant only to facilitate end-to-end testing, allowing us to force the "manual" login flow. If it ends up being useful we can un-hide it, but this seemed like the safest option to start with.
There is also a corresponding `--oidc-skip-listen` on the `pinniped get kubeconfig` command.

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 more restrictive library interface that more closely matches the use cases of our new form_post login flow.

This allows the prompts to be cancelled, which we need to be able to do in the case where we prompt for a manually-pasted auth code but the automatic callback succeeds.

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.

Our Supervisor callback handler now needs to load JS and CSS from the provider endpoint, and this JS needs to make a `fetch()` call across origins (to post the form to the CLI callback). This requires a custom Content-Security-Policy compared to other pages we render.

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.
After noticing that the upstream OIDC discovery calls can hang
indefinitely, I had tried to impose a one minute timeout on them
by giving them a timeout context. However, I hadn't noticed that the
context also gets passed into the JWKS fetching object, which gets
added to our cache and used later. Therefore the timeout context
was added to the cache and timed out while sitting in the cache,
causing later JWKS fetchers to fail.
This commit is trying again to impose a reasonable timeout on these
discovery and JWKS calls, but this time by using http.Client's Timeout
field, which is documented to be a timeout for *each* request/response
cycle, so hopefully this is a more appropriate way to impose a timeout
for this use case. The http.Client instance ends up in the cache on
the JWKS fetcher object, so the timeout should apply to each JWKS
request as well.
Requests that can hang forever are effectively a server-side resource
leak, which could theoretically be taken advantage of in a denial of
service attempt, so it would be nice to avoid having them.
- Add new optional ytt params for the Supervisor deployment.
- When the Supervisor is making calls to an upstream OIDC provider,
use these variables if they were provided.
- These settings are integration tested in the main CI pipeline by
sometimes setting them on deployments in certain cases, and then
letting the existing integration tests (e.g. TestE2EFullIntegration)
provide the coverage, so there are no explicit changes to the
integration tests themselves in this commit.
- this allows the oidc upsream watcher to honor the
HTTP_PROXY,HTTPS_PROXY,NO_PROXY environment variables
