[K8s] Fix for restart case

[MRiganSUSX]

Description

Fixes #589

When restarting, there is no native event that flags that the pod was deleted AND the resources (such as the name of the pod) cleaned up completely. Therefore we need to watch for notify on DELETED state + wait for the cleanup. There is an associated error code for the 'name still in use' so we use that as a flag.

Type of change

• Documentation (non-breaking change that adds or improves the documentation)
• New feature (non-breaking change which adds functionality)
• Optimization (non-breaking, back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)
• Breaking change (whatever its nature)

Key checklist

• All tests pass (eg. python -m pytest)
• Pre-commit hooks run successfully (eg. pre-commit run --all-files)

Further checks

• Code is commented, particularly in hard-to-understand areas
• Tests added or an issue has been opened to tackle that in the future.

Apologies for the big number of (apparent) changes, that is the result of ruff.

The important change is in create_pod for restart case.
