Generalized Consensus: Revocation and Candidacy

Hi HN, this is a series on a way to generalize consensus protocols and how to adapt them to existing systems.

This is part 6: It covers Revocation and Candidacy, the prerequisites for a leader change. We explain how to revoke previous leaderships and recruit for a new candidacy. It's a bit complex, but there are plenty of animations to help you along.

One of our goals is to make this approach work for Postgres via Multigres. But the principles can be used to implement your own solutions also. This will make Durability and High Availability more accessible for users.
