Add Governance Document for Infrastructure team

[MoralCode]

Starting to make a draft of a governance document for how the infra team votes on things .etc.

This is derived from the CollectOSS governance document, which itself is based on a CNCF template.

remaining TODOs:

• check some of the details of the infra team governance with the CHAOSS board (term, the final member list etc)
• does this team have an official name?
• remove or edit commented-out sections of this document to reflect this team's
• Verify that "lazy consensus by default, full team vote if requested" is a good model, or if we should skew more towards voting by default
• Make sure the team is on the same page with the shared values section (this was untouched relative to what is defined in CollectOSS and the template)
• Discuss with team and solicit collective review/voting on this governance so everyone is on the same page

https://github.com/kubernetes/community/blob/main/sig-k8s-infra/charter.md may be a better inspiration for a charter than the CollectOSS one...

Can we put a pause on this while the board has some discussions about the infrastructure committee?
