Produce state metrics on controller reconciliation requests

[aidandunlop]

Is your feature request related to a problem? Please describe

To enable more visibility of operator usage, improve debugging, and enable automatic alerting, each controller should produce metrics that increment upon a new operation e.g. Pipeline Created, Pipeline Updated, Pipeline Deleted.

This would also allow for correlation between Controller’s Reconcile requests and the Provider service CRUD operations

The metric(s) should contain details of the state of the operation, such as whether the operation failed or not and any error codes.
