Add support for NODE_OPTIONS for dd-trace (datadog agent)

[bmike78]

Prerequisites:

• Is the functionality available in the GitHub UI? If so, please provide a link to information about the feature.
  • technically this is a feature of the safe settings nodejs process

New Feature

• We run a forked copy of safe settings and would like to provide some contributions upstream to be at parity with main-enterprise.

• The feature we are looking to add is for NODE_OPTIONS and the addition of dd-trace to package.json for running a datadog sidecar as part of the pod deployment.

  • The helm chart would be updated as well to opt in with values for datadog to support the sidecar datadog-agent.

• This would allow for adding any NODE_OPTIONS, for any other auto instrumentation or just other nice to have options for garbage collection, etc..

@decyjphr, just looking for your initial feedback on this to see if this is a feature that you would accept. If so, we can work on adding this as a PR.

@decyjphr, another option for this that we can consider is that we use the opentelemetry agent npm package for automatic instrumentation as an additional dependency, since many of the common observability tools can ingest otel.
