1) change c++14 request from global to grpc-server only

2) change proto to llama/v1 dir according to lint suggestion

+# llama grpc server
+
+service as a grpc server to completion and embedding (when `--embedding` argument is given) based on examples/server.
+
+## running service
+
+run grpc-server command using argument like main program of llama.cpp with the following change:
+
+* add `--host` argument to set the listening host
+* add `--port` argument to set the listening port
+
+### behaving differences with examples/server
+
+* grpc-server will always break when <eos> is the predicted token.
