* feat: add provider metrics

This adds a counter metric `provider_api_calls_count` that observes
the results of upstream secret provider api calls.

(1) Observability
It allows an user to break down issues by provider and api call by
observing the status=error|success label. More details around the error
can be found in  the logs.

(2) Cost Management
Some providers charge by API calls issued. By providing observability
for the number of calls issued helps users to understand the impact of
deploying ESO and fine-tuning `spec.refreshInterval`.

(3) Rate Limiting
Some providers implement rate-limiting for their services. Having
metrics
for success/failure count helps to understand how many requests are
issued by a given ESO deployment per cluster.
