[RFC] TSC Chair definition and election procedure v2

[arm4b]

A follow-up to: #5071 where TSC Chair Election was initially suggested by @dzimine. This is a new revision proposal on top of that, covering governance inconsistencies.

When we defined "Leaders" we expected them (several persons) to take responsibility of:

External Relations, Organizational aspects, coordinating Events, Partnerships

TSC Meeting is an Organizational aspect and involves Event Coordination. TSC Chair is normally responsible for External Relations as well, including communicating with the LF (per Technical Charter) and being a project spokesperson. Having said that, role with many Leaders was previously created to reflect the TSC chairperson responsibilities and even more.

Now as team is gravitating towards the TSC Chair, the proposal is to move the StackStorm TSC governance model from Promotion (Leaders) to Election (TSC Chair). After reviewing tens of OSS Governance examples from different projects it's definitely more anticipated way for an average LF/CNCF project.

This version also defines new emeritus role "Project Mentor" for someone unique like project co-founder (as seen in some OSS Governance structures). Besides of being neutral mediator, advising members on fulfilling their responsibilities and helping project operating within best practices, Project Mentor holds election coordination responsibilities: ensuring proper announcements were made and in time, procedures are followed, calculating the election voting, the election results are communicated, deadlines are in place, etc.
