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

additionalScopes:
description: AdditionalScopes are the scopes in addition to "openid"
that will be requested as part of the authorization request
flow with an OIDC identity provider. In the case of a Resource
Owner Password Credentials Grant flow, AdditionalScopes are
the scopes in addition to "openid" that will be requested as
part of the token request (see also the AllowPasswordGrant field).
By default, only the "openid" scope will be requested.
items:
type: string
type: array
allowPasswordGrant:
description: AllowPasswordGrant, when true, will allow the use
of OAuth 2.0's Resource Owner Password Credentials Grant (see
https://datatracker.ietf.org/doc/html/rfc6749#section-4.3) to
authenticate to the OIDC provider using a username and password
without a web browser, in addition to the usual browser-based
OIDC Authorization Code Flow. The Resource Owner Password Credentials
Grant is not officially part of the OIDC specification, so it
may not be supported by your OIDC provider. If your OIDC provider
supports returning ID tokens from a Resource Owner Password
Credentials Grant token request, then you can choose to set
this field to true. This will allow end users to choose to present
their username and password to the kubectl CLI (using the Pinniped
plugin) to authenticate to the cluster, without using a web
browser to log in as is customary in OIDC Authorization Code
Flow. This may be convenient for users, especially for identities
from your OIDC provider which are not intended to represent
a human actor, such as service accounts performing actions in
a CI/CD environment. Even if your OIDC provider supports it,
you may wish to disable this behavior by setting this field
to false when you prefer to only allow users of this OIDCIdentityProvider
to log in via the browser-based OIDC Authorization Code Flow.
Using the Resource Owner Password Credentials Grant means that
the Pinniped CLI and Pinniped Supervisor will directly handle
your end users' passwords (similar to LDAPIdentityProvider),
and you will not be able to require multi-factor authentication
or use the other web-based login features of your OIDC provider
during Resource Owner Password Credentials Grant logins. AllowPasswordGrant
defaults to false.
