mod_http_oauth2: Revert role selector, going to try something else
Back out f2c7bb3af600
Allowing only a single role to be encoded into the grant takes away the
possibility of having multiple roles in the grant, one of which is
selected when issuing an access token. It also takes away the ability to
have zero roles granted, which could be useful e.g. when you only need
OIDC scopes.
