feat: updated new relic reporting to datadog

[muhammadadeeltajamul]

Removed new relic reporting and added datadog reporting to edx-ace
Added edx-django-utils and ddtrace

Test this by creating edx-platform PR with this package version

This is actually a good opportunity to stop referring to specific telemetry directly, and to start using edx-django-utils's abstraction layer as described at https://github.com/openedx/edx-django-utils/tree/master/edx_django_utils/monitoring (there's no need to set OPENEDX_TELEMETRY, since the IDA sets that, not the library). Here's what that would look like:

1. Delete the try block above
2. On this line, instead do from edx_django_utils.monitoring import set_custom_attribute
3. Delete report_to_datadog
4. Change report to call set_custom_attribute
5. Delete ddtrace from the requirements

If you're pinning edx-django-utils to a specific version, it should be explained in a comment and link to a ticket for removing the pin when the situation allows. Min-version constraints are fine, but capping the version interferes with routine upgrades and can cause "dependency hell" later. You can read more about this in OEP-18:

Looks good, although remember to update the changelog if you're planning on doing that post-release.
