OAuth2 support requires that only tokens associated with users may be used with authenticated resources. However, OAuth2 also support a client credentials grant type which does not require any user interaction. This is typically used directly by applications to access such API. This does not work with RESTful as once a resource is marked as authenticated, there has to be an associated user. This change allows plugin developers to specify a user which will be used when a client credentials token is used. The user may be specified with the uid or name. The uid has the higher priority.
Currently, we use two pieces of information for OAuth2 authentication - server and scope. We define them as separate items in the plugin definition. There might be more items required in the future (one of which could be support for client credentials in RESTful-Drupal#944). It might be cleaner to change all the definitions to an array.

This implementation is getting complex. That is fine because this is a complex integration.
However we missed in the last iteration one of the key factors of RESTful, which is providing an Example on how to use all these features.
This PR is blocked by #945. Once that one is merged this one should be adapted to use the same structure.
THANKS for the great work. Sorry it took so long, but I am currently spread too thin across multiple contribs and core.

We are loading the user by name and then by id. We should load the user only once.

Is there any impediment to make it camel case? If not, I'd rather camel case since it's consistent with the rest of the annotation keys.
