bc828e939a raft: pull checkQuorumActive into prs 
It's looking at each voter's Progress and needs to know how quorums
work, so this is the ideal new home for it.

a6f222e62d raft: establish an interface around vote counting 
This cleans up the mechanical refactor in the last commit and will
help with etcd-io/etcd#7625 as well.

a11563737c raft: use progress tracker APIs in more places 
This doesn't completely eliminate access to prs.nodes, but that's not
really necessary. This commit uses the existing APIs in a few more
places where it's convenient, and also sprinkles some assertions.

dbac67e7a8 raft: extract progress tracking into own component 
The Progress maps contain both the active configuration and information
about the replication status. By pulling it into its own component, this
becomes easier to unit test and also clarifies the code, which will see
changes as etcd-io/etcd#7625 is addressed.

More functionality will move into `prs` in self-contained follow-up commits.

MAINTAINERS: remove fanmin shi 
I no longer have the time to maintain etcd as my career takes me to a different direction; Hence, I think it is appropriate to remove myself from the maintainer responsibility.

Working on etcd project was one of the most challenging and rewarding experiences I ever had. Thanks @xiang90 @gyuho @heyitsanthony @philips

9a6f7d4361 README: update handling of security vulnerabilities 
We may not want to suggest to contact CoreOS now. We could remove this
section but consiering the nature of the subject, discussion with the project
maintainers probably a good idea if someone doesn't find it comfortable
to report an issue right away.

39bbc66b46 Doc: create issue and PR management guidelines 
I would like to propose a formal guide for issue triage and PR management.
This should help us keep open issues and PRs under a desirable numbers.
For example, keep issues under 100. These guidelines should specially help
manage and close issues and PRs that are inactive in a timely manner.
