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

## 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..
