    Implement caching for Tokens and Token Validation

    Based upon the keystone caching (using dogpile.cache) implementation
    token caching is implemented in this patchset.

    This patchset inclues basic Token caching as the first implemntation
    of this caching layer. The following methods are cached:
        * token_api.get_token,
        * token_api.list_revoked_tokens
        * token_provider_api.validate_v3_token
        * token_provider_api.check_v3_token
        * token_provider_api.check_v2_token
        * token_provider_api.validate_v2_token
        * token_provider_api.validate_token

    Calls to token_api.delete_token and token_api.delete_tokens will
    properly invalidate the cache for the tokens being acted upon, as
    well as invalidating the cache for the revoked_tokens_list and the
    validate/check token calls.

    Token caching is configurable independantly of the revocation_list
    caching.

Also another patchset worked on this, but consolidating all doc impact to this single bug.

    Implement Caching for Token Revocation List

    Based upon the Keystone caching (using dogpile.cache) implementation
    token revocation list caching is implemented in this patchset.

    The following methods are cached:
        * token_api.list_revoked_tokens

    Calls to token_api.delete_token and token_api.delete_tokens will
    properly invalidate the cache for the revocation list.
