1354484 - Annotate New Relic transactions with request User Agent

Status: RESOLVED FIXED

(Tree Management :: Treeherder: Infrastructure, enhancement, P3)

Description

[Ed Morley [:emorley]]

Earlier I was trying to track down which tool is making requests to the deprecated ArtifactViewSet.list() endpoint (which has only returned HTTP 405s for some time), however was unable to do so, since the User Agent isn't visible in Insights (even though it appears in the errors panel and slow transactions view).

I previously reported this to New Relic (https://support.newrelic.com/tickets/172627/edit), who said they've entered a feature request, but for now if we want the user agent there, we'll have to add it as a custom attribute, to make it report for all requests and not just slow/failing ones.

Bug 1354484 - Rename whitenoise_custom.py to middleware.py

Since we're about to add more Treeherder-specific middleware. Also moves
it outside of `config/` to a more usual location for Django projects.

Bug 1354484 - Report request User Agent to New Relic

This is required since the New Relic Python agent only submits the User
Agent to APM (which only handles certain transactions) and not also to
Insights:

The attributes of requests are documented here:
