auth: oauth2.go diff

Log ignored errors, grant revocations can return an error. Turn a few TODOs for logging errors into calls to log the actual error. Change the return type of grant revocations for GrantTypes to an error, so they can be logged by the system, not each GrantType. Implement a stub of the revocation function for the authcode GrantType.
