Project governance: tweak voting majority threshold

[kenhys]

Describe the bug

Currently, the voting requires 2/3 majority which is described in Voting

More contributors involved, it tends to be hard to satisfy with 2/3 majority if there are many inactive maintainers in the future.

Also mentioned https://github.com/fluent/fluentd/issues/4150#issuecomment-1507874478

Expected behavior

Introduce the new threshold in a practical manner.

Instead of 2/3 majority, changes the threshold like this:

UPDATED: based on https://github.com/fluent/fluentd/issues/4151#issuecomment-1526998656

• No objection ballot
• At least effective 3-person affirmative vote
• At least effective 2-organization affirmative vote
  • Effective organization affirmative vote means:
    • One member of the organization made an affirmative vote (even though other colleagues didn't vote, it was treated as an effective affirmative organization vote)
    • An affirmative vote of a member not belonging to an organization is considered as one organization's affirmative vote
• At least 2-week for voting

Some ballot scenario:

• effective 3-person (all individual) affirmative vote 🙋🙋‍♂️🙋‍♀️=> approved

• effective 3-person (1 individual🙋, 2 person who belong to the same organization🙋‍♂️🙋‍♂️) affirmative vote => approved

• effective 3-person (1 organization🙋, 2 individuals🙋‍♂️🙋‍♀️) => approved

• effective 3-person but, who belong to the same organization 🙋🙋🙋 => declined

• effective 3-person but 1 objection 🙋🙋🙅‍♂️ => declined

The important point is not to be dominated by certain organizations and to make the project's decisions by maintainers appropriately.

Additional context

• If these change was introduced, the previous organization's vote was easy to make things forward.

• Before call for voting #4150, this issue should be processed. (it makes easy to process #4150 afterwards)

• well-known similar voting threshold is mentioned https://github.com/fluent/fluentd/issues/4150#issuecomment-1507874478

ref: code modifications and veto of Apache Voting Process

• https://www.apache.org/foundation/voting#apache-voting-process

  the proposal requires three positive votes and no negative votes in order to pass

For the record, the previous proposal:

• ~~No objection ballot~~
• ~~At least effective 3-organization affirmative vote~~

~~Both of the above conditions are met, the voting agenda will be approved.~~
