Lance Bragstad f463bdccf1 Validate identity providers during token validation
Previously, it was possible to validate a federated keystone token
after the identity provider associated by that token was deleted,
which is a security concern.

This commit does two things. First it makes it so that the token
cache is invalidated when identity providers are deleted. Second,
it validates the identity provider in the token data and ensures it
actually exists in the system before considering the token valid.

[`bug 1291157 <https://bugs.launchpad.net/keystone/+bug/1291157>`_]
Identity provider information is now validated in during token validation.
If an identity provider is removed from a keystone service provider, tokens
associated to that identity provider will be considered invalid.
