- Add `AllowPasswordGrant` boolean field to OIDCIdentityProvider's spec
- The oidc upstream watcher controller copies the value of
`AllowPasswordGrant` into the configuration of the cached provider
- Add password grant to the UpstreamOIDCIdentityProviderI interface
which is implemented by the cached provider instance for use in the
authorization endpoint
- Enhance the IDP discovery endpoint to return the supported "flows"
for each IDP ("cli_password" and/or "browser_authcode")
- Enhance `pinniped get kubeconfig` to help the user choose the desired
flow for the selected IDP, and to write the flow into the resulting
kubeconfg
- Enhance `pinniped login oidc` to have a flow flag to tell it which
client-side flow it should use for auth (CLI-based or browser-based)
- In the Dex config, allow the resource owner password grant, which Dex
implements to also return ID tokens, for use in integration tests
- Enhance the authorize endpoint to perform password grant when
requested by the incoming headers. This commit does not include unit
tests for the enhancements to the authorize endpoint, which will come
in the next commit
- Extract some shared helpers from the callback endpoint to share the
code with the authorize endpoint
- Add new integration tests
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").

It turns out that `syscall.Stdin` is of type `int` on Linux and macOS, but not on Windows (it's `syscall.Handle`). This should now be portable and do all the require type casting on every platform.

For CLI-based auth, such as with LDAP upstream identity providers, the
user may use these environment variables to avoid getting interactively
prompted for username and password.
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

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.

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.

- Also some light prefactoring in login.go to make room for LDAP-style
login, which is not implemented yet in this commit. TODOs are added.
- And fix a test pollution problem in login_oidc_test.go where it was
using a real on-disk CLI cache file, so the tests were polluted by
the contents of that file and would sometimes cause each other to
fail.
We have some nice normalization code in this package to remove expired or otherwise malformed cache entries, but we weren't calling it in the appropriate place.
Added calls to normalize the cache data structure before and after each transaction, and added test cases to ensure that it's being called.

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 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.
There is also a small typo fix in some flag usages (s/RF8693/RFC8693/)

- The overall timeout for logins is increased to 90 minutes.
- The timeout for token refresh is increased from 30 seconds to 60 seconds to be a bit more tolerant of extremely slow networks.
- A new, matching timeout of 60 seconds has been added for the OIDC discovery, auth code exchange, and RFC8693 token exchange operations.
The new code uses the `http.Client.Timeout` field rather than managing contexts on individual requests. This is easier because the OIDC package stores a context at creation time and tries to use it later when performing key refresh operations.

Before this, we weren't properly parsing the `Content-Type` header. This breaks in integration with the Supervisor since it sends an extra encoding parameter like `application/json;charset=UTF-8`.
This change switches to properly parsing with the `mime.ParseMediaType` function, and adds test cases to match the supervisor behavior.

I think this should be more correct. In the server we're authenticating the request primarily via the `subject_token` parameter anyway, and Fosite needs the `client_id` to be set.

This refactors the `UpstreamOIDCIdentityProviderI` interface and its implementations to pass ID token claims through a `*oidctypes.Token` return parameter rather than as a third return parameter.

This is just a more convenient copy of these values which are already stored inside the ID token. This will save us from having to pass them around seprately or re-parse them later.
