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

- Note that this adds an extra check of the response, which is that
the issuer string in the response must match issuer of the requested
URL.
- Some of the error messages also changed to match the errors provided
by oidc.NewProvider
- And perform auto-discovery when the flags are not set
- Several TODOs remain which will be addressed in the next commit

- 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.
This isn't strictly necessary because we currently always have the concierge endpoint and CA as CLI flags, but it doesn't hurt and it's better to err on the side of _not_ reusing a cache entry.

Before this change, the "context", "cluster", and "user" fields in generated kubeconfig YAML were always hardcoded to "pinniped". This could be confusing if you generated many kubeconfigs for different clusters.
After this change, the fields will be copied from their names in the original kubeconfig, suffixed with "-pinniped". This suffix can be overridden by setting the new `--generated-name-suffix` CLI flag.
The goal of this change is that you can distinguish between kubeconfigs generated for different clusters, as well as being able to distinguish between the Pinniped and original (admin) kubeconfigs for a cluster.

We were previously issuing both client certs and server certs with
both extended key usages included. Split the Issue*() methods into
separate methods for issuing server certs versus client certs so
they can have different extended key usages tailored for each use
case.
Also took the opportunity to clean up the parameters of the Issue*()
methods and New() methods to more closely match how we prefer to call
them. We were always only passing the common name part of the
pkix.Name to New(), so now the New() method just takes the common name
as a string. When making a server cert, we don't need to set the
deprecated common name field, so remove that param. When making a client
cert, we're always making it in the format expected by the Kube API
server, so just accept the username and group as parameters directly.
This adds two new flags to "pinniped get kubeconfig": --skip-validation and --timeout.
By default, at the end of the kubeconfig generation process, we validate that we can reach the configured cluster. In the future this might also validate that the TokenCredentialRequest API is running, but for not it just verifies that the DNS name resolves, and the TLS connection is available on the given port.
If there is an error during this check, we block and retry for up to 10 minutes. This duration can be changed with --timeout an the entire process can be skipped with --skip-validation.
