Release v9.1.0 Redux

[bizob2828]

Proposed Release Notes

• Added experimental loader to support instrumentation of CommonJS packages in ECMAScript Module(ESM) applications.

  • It only supports versions of Node.js >= 16.12.0.
  • It is subject to change due to its experimental stability.

• Enhanced supportability metrics for ESM support.

  • Added new metrics to track usage of ESM loader(Supportability/Features/ESM/Loader and Supportability/Features/ESM/UnsupportedLoader).
  • Updated instrumentation map to include an optional "friendly name" for tracking metrics.

• Enabled re-throwing ESM import errors of newrelic.js so that the user is informed to rename it to newrelic.cjs

• Fixed an issue with mongodb instrumentation where IPv6 address([::1]) was not getting mapped to localhost when setting the host attribute on the segment.

• Added a test ESM loader to properly mock out agent in versioned tests.

• Added ESM versioned tests for: express, pg, mongodb, and @grpc/grpc-js.
