Add OS-FEDERATION to scoped federation tokens

[Steve Martinelli]

Currently, when a federated user gets a token, it has an OS-FEDERATION section under 'user', which contains information about the idp and protocol.

However when the same user uses the unscoped token to get a scoped token, we should put the same information in there as well. This will help support revocation events for federated tokens, i.e. revoking all tokens based on IDP id.

    Add an OS-FEDERATION section to scoped federation tokens

    In this change, we add an OS-FEDERATION section to the user
    section in a scoped federation token. We currently do the same
    for unscoped tokens. This will also help with revocation events,
    specifically revoking tokens based on IDP id.
