fix: Feature category metrics generation from Sidekiq SLIs
This makes sure that we can generate feature category metrics from our Sidekiq SLIs.
Before this change we would be generating the
rules/autogenerated-feature-category-metrics-sidekiq.yml
file after
we had already generated the regular file. So the latter would take
presedence in the JSON object we geed into jsonnet-tool.
This moves those recordings to a new file, which means that the
recordings in the
rules/autogenerated-feature-category-metrics-sidekiq.yml
are the
ones generated from the Sidekiq-SLIs directly. While the ones in
rules/autogenerated-custom-feature-category-metrics-sidekiq.yml
are
the ones for Sidekiq jobs that we'll improve upon in
gitlab-com/gl-infra&700 (closed)
This was needed so stage groups can add their own SLIs to Sidekiq, for example in !5017 (merged)
