The following revision is made.

  1. The clientRequests become a variable, which uniquely identified each request received by server.
  2. Only valid message is evaluated, to reduce state space.
  3. Add test to see if there are more than one Leader per term in the cluster.
  4. Add test to see if the committedLog is consistent.

Thanks @jinlmsft. Looks like there's a few little things in here, mostly good but probably needing to be teased apart and cleaned up. Given that I'm not actively working on the spec, I'll leave this PR open more or less indefinitely and link to it from the README. Hopefully people that are trying to apply the model checker will look here.

Remove unused variable committedLog.

The variable committedLog is not part of the original Raft specification
but was introduced later in the still open pull request
ongardie/raft.tla#4.
