The 'googleapis' library is too large size

[anchan828]

I was using webpack-bundle-analyzer to check the included libraries and found that the googleapis library contains 16MB.
Since this library is only used by @google-cloud/opentelemetry-cloud-monitoring-exporter, could it be replaced by @google-cloud/monitoring instead?

Thanks for opening an issue about this

could it be replaced by @google-cloud/monitoring instead

I think this would be a great enhancement but don't have time to work on it right now. Leaving it up for grabs
