capabilities: report capabilities from backend

Use the Backend interface to report Backend capabilities. Previously,
these were reported via a DirectoryInfo message, however they have
nothing to do with a directory and should be reported directly by the
backend. Add Capabilities method to Backend interface, satisfy this in
each backend, and use it on the UI side.

Remove Caps field from DirectoryInfo
