Reduce resource contention on picking CI builds during `jobs/request` [RUN ALL RSPEC] [RUN AS-IF-FOSS]

Merged Kamil Trzciński | OoO 2022.07.23 till 2022.08.20 requested to merge ci_temporary_lock into master

What does this MR do?

Based on !55194 (merged). It will automatically be retargeted on master upon merge.

Introduce a temporary lock on a resource allowing us to quickly skip build from the queue instead of performing an expensive database optimistic lock status transition

This should reduce a rate of runners competing for the same resource, but still allowing them to recover right after.

I wonder, how impact it will have on Redis calls. It should be pretty cheap.

Does this MR meet the acceptance criteria?
