fix(cloud-monitoring-exporter)!: update to stable OTel metrics version

[aabmass]

Fixes #379
Fixes #129
Fixes #101

Lots of changes to upgrade to the latest (stable) version of OTel metrics.

I removed all of packages/opentelemetry-cloud-monitoring-exporter/test/transform.test.ts in favor of snapshot/golden tests I am adding in the next PR: #447.

Note codecov is failing because of the deleted tests
