[gnmi] Remove gNMI from sweetcomb

Reasons for removing it:

-This gNMI server has been upgraded to a more stable form.
-It should live in a separate project because gNMI server is only
dependant of sysrepo not of VPP or sweetcomb.
-There were strange dependencies to this implementation like an XML parser
 library.
-Capabilities RPC was answering wrong version number (1001 instead of
0.7.0) and encodings (ASCII vs JSON).
-Error codes were not return to client in case of problem of configuration.
Typically for element not found.
-This server uses sysrepo C API though bindings for C++ can be obtained.
-Documentation was missing.
-Set RPC could not identify a key in a YANG list because a YANG library
must be used for this not just a JSON parser.
-It would be difficult to adapt this server to support more encodings
than JSON. The new gNMI server offers an easier way to add encodings.
-Log control level has been implemented in the new gNMI server.
-Subscribe RPC has been added to the new server.
