V3 tokens do not show up in list_tokens_for_trust

[Adam Young]

Listing tokens for a trust is based on the values in extra, which changes format between V2 and V3. Thus, tokens associated with a trust do not show up when listing tokens for a trust if they are V3 tokens.

    extracting user and trust ids into normalized fields

    These fields are used for queries, and may need to be indexed
    Also moves the delete token for... functions into the base class
    for controllers.

    Removed the token API revoke token call as that needed access to other
    APIs. Logic was moved into the controller.
