* Reland "Added IsolateNameServer functionality (#5410)" This reverts commit c3976b3c7183f479717bffed3f640fb92afbd3dc. * Fixed issue with isolate_name_server_test which caused test to timeout * Disabled thread_annotations on Android as they aren't supported in the NDK headers for std::mutex. Readded thread annotations to IsolateNameServer.
