UUID Token provider in keystone.conf must be set when token_format = UUID

[Dolph Mathews]

This review [1] illustrates that if token_format is explicitly set to UUID, then the token provider is not set by keystone correspondingly (this should happen automatically).

token_format = UUID should take precedence to provide backwards compatibility with existing configurations. If a token provider is explicitly set, then that should take precedence over token_format (or an error should be raised if they don't match).

If no one has started on working this one yet, I'll take care of it today since I created this mess.

    Support token_format for backward compatibility

    The provider property in the [token] section will be unset by default. If
    provider is not set, we will use token_format in the [signing] section to
    determine to provider. If provider is set, it must agree with the token_format.
