Replace the controller and action label with a single label formatted like `caller_id` in metrics
We currently log controller
and action
in separate labels for some metrics: https://gitlab.com/gitlab-org/gitlab/blob/9d7c81eea9a5143aa9ca847da71ae366265f70c0/lib/gitlab/metrics/transaction.rb#L10.
For the API, we put in "Grape" for controller. Would it be worth to replace these 2 labels with a single caller_id
like field that we use in the logs?
