Make ServerInfo accessible by plugins

The ServerInfo information provides information about the server
configuration that is relevant for rendering the UI. UI plugins should
be able to access it, e.g. they need the anonymous coward name to
render user names the same way as Gerrit core does (use the anonymous
coward name if the user has no full name).
