Add more unit tests for dynamic clients and enhance token exchange - Enhance the token exchange to check that the same client is used compared to the client used during the original authorization and token requests, and also check that the client has the token-exchange grant type allowed in its configuration. - Reduce the minimum required bcrypt cost for OIDCClient secrets because 15 is too slow for real-life use, especially considering that every login and every refresh flow will require two client auths. - In unit tests, use bcrypt hashes with a cost of 4, because bcrypt slows down by 13x when run with the race detector, and we run our tests with the race detector enabled, causing the tests to be unacceptably slow. The production code uses a higher minimum cost. - Centralize all pre-computed bcrypt hashes used by unit tests to a single place. Also extract some other useful test helpers for unit tests related to OIDCClients. - Add tons of unit tests for the token endpoint related to dynamic clients for authcode exchanges, token exchanges, and refreshes.

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"
