bad95c072e Upgrade project dependencies to latest
- Upgrade Go used in CI from 1.19.0 to 1.19.1
- Upgrade all go.mod direct dependencies to latest available versions
- Upgrade distroless base image to latest available version
- Upgrade Go fips compiler to to latest available version

Note that upgrading the go-oidc library changed an error message
returned by that library, so update the places where tests were
expecting that error message.

c6c2c525a6 Upgrade the linter and fix all new linter warnings
Also fix some tests that were broken by bumping golang and dependencies
in the previous commits.

Note that in addition to changes made to satisfy the linter which do not
impact the behavior of the code, this commit also adds ReadHeaderTimeout
to all usages of http.Server to satisfy the linter (and because it
seemed like a good suggestion).

22fbced863 Create username scope, required for clients to get username in ID token
- For backwards compatibility with older Pinniped CLIs, the pinniped-cli
  client does not need to request the username or groups scopes for them
  to be granted. For dynamic clients, the usual OAuth2 rules apply:
  the client must be allowed to request the scopes according to its
  configuration, and the client must actually request the scopes in the
  authorization request.
- If the username scope was not granted, then there will be no username
  in the ID token, and the cluster-scoped token exchange will fail since
  there would be no username in the resulting cluster-scoped ID token.
- The OIDC well-known discovery endpoint lists the username and groups
  scopes in the scopes_supported list, and lists the username and groups
  claims in the claims_supported list.
- Add username and groups scopes to the default list of scopes
  put into kubeconfig files by "pinniped get kubeconfig" CLI command,
  and the default list of scopes used by "pinniped login oidc" when
  no list of scopes is specified in the kubeconfig file
- The warning header about group memberships changing during upstream
  refresh will only be sent to the pinniped-cli client, since it is
  only intended for kubectl and it could leak the username to the
  client (which may not have the username scope granted) through the
  warning message text.
- Add the user's username to the session storage as a new field, so that
  during upstream refresh we can compare the original username from the
  initial authorization to the refreshed username, even in the case when
  the username scope was not granted (and therefore the username is not
  stored in the ID token claims of the session storage)
- Bump the Supervisor session storage format version from 2 to 3
  due to the username field being added to the session struct
- Extract commonly used string constants related to OIDC flows to api
  package.
- Change some import names to make them consistent:
  - Always import github.com/coreos/go-oidc/v3/oidc as "coreosoidc"
  - Always import go.pinniped.dev/generated/latest/apis/supervisor/oidc
    as "oidcapi"
  - Always import go.pinniped.dev/internal/oidc as "oidc"

b981055d31 Support revocation of access tokens in UpstreamOIDCIdentityProviderI
- Rename the RevokeRefreshToken() function to RevokeToken() and make it
  take the token type (refresh or access) as a new parameter.
- This is a prefactor getting ready to support revocation of upstream
  access tokens in the garbage collection handler.

d0ced1fd74 WIP towards revoking upstream refresh tokens during GC
- Discover the revocation endpoint of the upstream provider in

  by the garbage collector controller
- Adds RevokeRefreshToken to UpstreamOIDCIdentityProviderI
- Implements the production version of RevokeRefreshToken
- Implements test doubles for RevokeRefreshToken for future use in
  garbage collector's unit tests
- Prefactors the crud and session storage types for future use in the
  garbage collector controller
- See remaining TODOs in garbage_collector.go

a34dae549b When performing an upstream refresh, use the configured http client
Otherwise, the CA and proxy settings will not be used for the call
to the upstream token endpoint while performing the refresh. This
mistake was exposed by the TestSupervisorLogin integration test, so
it has test coverage.

79ca1d7fb0 Perform an upstream refresh during downstream refresh for OIDC upstreams
- If the upstream refresh fails, then fail the downstream refresh
- If the upstream refresh returns an ID token, then validate it (we
  use its claims in the future, but not in this commit)
- If the upstream refresh returns a new refresh token, then save it
  into the user's session in storage
- Pass the provider cache into the token handler so it can use the
  cached providers to perform upstream refreshes
- Handle unexpected errors in the token handler where the user's session
  does not contain the expected data. These should not be possible
  in practice unless someone is manually editing the storage, but
  handle them anyway just to be safe.
- Refactor to share the refresh code between the CLI and the token
  endpoint by moving it into the UpstreamOIDCIdentityProviderI
  interface, since the token endpoint needed it to be part of that
  interface anyway

Ryan Richard
84c3c3aa9c Optionally allow OIDC password grant for CLI-based login experience
- 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
