Additional context

The latest version of OpenCensus is pinned to google-cloud-monitoring version 1.82.0, which is from July 2019. It has transitive dependency on old version of gax-grpc which is incompatible with the more recent versions of gax and grpc libraries. Bumping google-cloud-monitoring to the latest version 2.0.8 will fix this problem.
