CJ job to bump provider to RC versions in constraints of RC Airflow

[potiuk]

Sometimes we have a neeed to use RC provider version in RC candidate of airflow when the provider has not been released yet but we want to use it regardless. This happened for example with 2.10.3rc2 which would be best if installed wth 1.5.0rc2 of apache-airflow-providers-fab.

This could be automated as a separate CI, manually triggerable job that could upate the constraints - similar to the "release image" joib we have for release manager.

This job should look as follows:

Three parameters:

airflow version: x.y.zrcn
provider name; PROVIDER
provider version to use: X.Y.ZrcN

• find constraints-x.y.zrcn tag
• branch off from that tag and create a branch constraints-x.y.zrcn-fix (or use it if already there)
• modify, commit and push apache-airlfow-providers-PROVIDER lines to use ==X.Y.ZrcN in all constraint files in this tag
• move tag the new commit wtih constraints-x.y.zrcn

Don't we need to run the dependency to make sure it actually works?
Manually changing the line in the constraint file will work only if the dependencies of previous version agrees with the new version.

That's for exceptional cases when they differ enough (or are == for example). But we could writte this job to do full dependency resolution as well.

Not needed any more. We handle it automatically with --pre flag when preparing pre-release images and skipping unreleased providers from constraints.
