Metric specific to workflow retries per namespace

[Tihomir Surdilovic]

Currently we seem to only have workflow_retry_backoff_timer
available to check for count of workflow retries.

Feature request is to add workflow_retried counter metric that would be able to be filtered by namespace.

Thanks.

@tsurdilo how are user going to use this metrics? Do we need to tag the workflowID on the metrics? That will have cardinality issue.

The attempt count should also be available from within workflow. I think workflow.GetInfo() should return it already.

Hi folks, @tsurdilo was kind enough to make this issue from a conversation we were having on Slack. Basically, we are in a situation where we manage the control plane, but not the workflows themselves. We would like to know the global retry count, ideally by namespace, at a given time.
