security: add support for disabling users

This change adds support for disabling users. Users can be disabled by setting the enabled
property to false and the AuthenticationService will check to make sure that the user is enabled.
If the user is not enabled, this will be audited as an authentication failure.

Also as part of this work, the AnonymousUser was cleaned up to remove having a static instance
that caused issues with tests.

Finally, the poller of users was removed to simplify the code in the NativeUsersStore. In our other
realms we rely on the clear cache APIs and the timeout of the user cache. We should have the
same semantics for the native realm.

Closes elastic/elasticsearch#2172
