🐛 Fix cancel not working on Kube deployment since 0.29.13-alpha. (air…

…bytehq#5850)

A few days ago we removed the workflow volume from the Kubernetes deployment in order to simplify the set up. This also lets us do away with the workspace PVC.

In theory this isn't needed since the volume is mainly used for logs and our Kube deployment logs out to the Cloud storage.

In the process of doing so, we realised the volume is used to store the temporal workflow id that is later used to cancel the workflow. Thus cancellations stopped working.

This PR:

Adds a migration to add the temporalWorkflowId column to the Attempts table. Exposes various persistent methods for this.
Modify temporal to store the workflow id in this column. Modify cancellation to retrieve the workflow id from the table.
Things to call out:

This approach means the worker now requires access to the jobs DB. I think this is reasonable.
Some tests are disabled since we haven't really stabilised the Flyway + older file-base migrations yet. Follow up ticket has been created (Update config and job persistence unit tests to run migrations airbytehq#5857) and Liren is working on this.
