[puppet] Propose retiring puppet-glare

Hello,

I'd like to propose retiring puppet-galre project, because the Glare[1] project looks inactive for a while based on the following three points - No actual development is made for 2 years - No release was made since the last Rocky release - setup.cfg is not maintained and the python versions listed are very outdated

I'll wait for 1-2 weeks to hear opinions from others. If anybody is interested in keeping the puppet-glare project or has intention to maintain Glare itself then please let me know.

Thank you, Takashi
