[APM] Remove direct references to newrelic

[timmc-edx]

We have some code in edx-platform (and possibly elsewhere) that directly imports and uses newrelic rather than going through edx-django-utils (e.g. in StaticContentServer). These all need to be switched over to edx-django-utils.

A/C:

• [x] Remaining newrelic references in codebase identified
• [x] References replaced with edx_django_utils calls or ticketed for dealing with later

Worklist:

• [x] newrelic refs in edxapp: https://github.com/openedx/edx-platform/pull/34781
• [x] Inform owning teams about other instances of import.*newrelic or newrelic.*import:
  • [x] openedx/ecommerce -- purchase
  • [x] openedx/edx-ace -- infinity
  • [x] openedx/xqueue -- aurora
  • [x] openedx/edx-notes-api -- aurora
  • [x] openedx/course-discovery -- phoenix
  • [x] edx/edx-analytics-dashboard -- cosmonauts
• [x] Determine what to do with edx_django_utils features that only support NR
  • For example: https://github.com/openedx/edx-platform/blob/d3ffb3e88270ee6ac8a7b45eeff9d5aec4a5726d/lms/djangoapps/courseware/block_render.py#L941
  • Filed https://github.com/openedx/edx-django-utils/issues/419 to cover this.

Maybe most of this should be about informing maintainers?

[timmc-edx]

Yeah. I've gone ahead and just notified each team; they can migrate on their own schedule. I think the only thing left is this set_monitoring_transaction_name issue and I'm inclined to suggest that the owning team of the relying code should plan to set a new span tag and use that instead in their new dashboards and alerts (and we can deprecate that from e-d-u.)

[robrap]

I think the only thing left is this set_monitoring_transaction_name issue ...

Could we just document that as not being available for certain backends, in addition to your intended communications?

[timmc-edx]

It's already documented: https://github.com/openedx/edx-django-utils/tree/master/edx_django_utils/monitoring#choice-of-monitoring-tools

I haven't gone through and checked if other such newrelic-specific functions are used in the codebase, though.

Filed https://github.com/openedx/edx-django-utils/issues/419 to cover the remaining NR-specific functions.
