Move logging into worker processing loop: (#882)

## Description


This sets a new logger with values for each loop. Previously the loop was being set outside of the loop and all `.With` functions persisted across loops. This made the logs almost unreadable when multiple workflows were run by a single worker.

## Why is this needed



Fixes: #

## How Has This Been Tested?





## How are existing users impacted? What migration steps/scripts do we need?





## Checklist:

I have:

- [ ] updated the documentation and/or roadmap (if required)
- [ ] added unit or e2e tests
- [ ] provided instructions on how to upgrade
