Build CPP interop client in Git-on-[] as well as in [].

To build client in Git-on-[]:
# regenerate Makefile
net/grpc/tools/buildgen/generate_projects.sh
# generate .pb.h and .pb.cc
protoc --cpp_out=. --grpc_out=. --plugin=protoc-gen-grpc=[]-bin/net/grpc/compiler/cpp_plugin  net/grpc/cpp/test/interop/test.proto net/grpc/cpp/test/interop/empty.proto net/grpc/cpp/test/interop/messages.proto
# Complile and link
net/grpc/tools/build_grpc_dev.sh bins/interop_client

To test against GFE/ESF:
# bring up server
[] build net/grpc/testing/interop:server_components_env
[]-bin/net/grpc/testing/interop/server_components_env --manual --rpc_port=25000
# start client
/tmp/grpc-codebase/bins/interop_client --enable_ssl=true --server_port="server ssl port listening port"

To test [] build against GFE/ESF:
[] run net/grpc/cpp:interop_client  --  --enable_ssl=true --server_port="server ssl port listening port"
