[ClusterLabs] [IMPORTANT] Upcoming changes to all ClusterLabs, corosync and knet repositories

[Fabio M. Di Nitto]

All,

following the current internet trends, all our github repositories will 
switch from the "master" branch to "main".

This email is not meant to spark any discussion around the merit of 
those trends or offend anyone, it´s simple and technical and I would 
like to keep it that way.

This is a multiple day transition that will start the 27th of Dec and 
end hopefully by the 30th of Dec.

The repositories change will follow the published guideline from github:
https://github.com/github/renaming

and this will happen the 27th itself, pretty fast and hopefully painless.

Upstream CI is the most affected service by this change. During those 
days CI will be unavailable or bumpy.

Jenkins itself needs to do an internal transition to change the "master" 
node name, plus all the CI jobs configurations and all the helper scripts.

There will be for sure disruptions in CI after the fact (for example all 
the CI generated repo files will be renamed).

Details of those changes will be published after the transition is 
completed. If you have any external service / scripts relying on CI 
builds, be ready to adjust. I am not planning to add backward 
compatibility layers around.

Cheers
Fabio
