Support multi-job workflows

[sdgluck]

Hey great action, and I'd love to use it in our org.

The only issue is that our deploy workflow has over ten separate jobs.

AFAICT, at the moment this action only supports locking within the context of a single job?

What changes would be necessary to be able to support locking and unlocking in different jobs? Say, the first and last job in a workflow would do the locking and unlocking respectively. I envisage something like an input to the action which specifies whether it should perform a lock or unlock operation. When specifying the unlock, the user job would have an if: always() condition.

Look forward to hearing your thoughts.

Hey @sdgluck, so sorry on the delay on this. I've been meaning to respond for weeks.

Anyways, the changes would be minimal overall, I think? I don't know if there's a way to conditionally run the post-entrypoint but if there is, we could have some kind of mode for which way to run.

The reason I wanted to use the post-entrypoint was to basically guarantee an unlock even if you forgot the if: always().

Do you actually need to lock everything over your 10 separate jobs? Can you lock each one individually?
