Summary

This task captures the work necessary to generate a Tekton task to update all release specific configuration in the installer's repositories.

Requirements

1. Update the Prow configuration and create branches for the following repos:

• backplane-must-gather
• bailer
• multiclusterhub-operator
• backplane-operator
• discovery

2. Update branch references in backplane-operator 
  - See https://github.com/stolostron/backplane-operator/pull/381 for an example

3. Update branch references and versions in multiclusterhub-operator
  - See https://github.com/stolostron/multiclusterhub-operator/pull/965 for an example

Output

A Tekton task that, when armed with the correct access credentials, will take as input a target source release and release branch and open a pull request with the changes necessary to initialize a new target release stream for the installer.

This task should be formatted in such a way that it can be gated by previous tasks in the invocation chain related to automated release cut over.
