raft: use a singleton global rand
...
rand.NewSource creates a 4872 byte object. With a small number of raft
groups in a process this isn't a problem. With 10k raft groups we'd use
46MB for these random sources. The only usage is in
raft.resetRandomizedElectionTimeout which isn't performance critical.
Fixes #6347 .

raft: Allow an election immediately after start with checkQuorum
...
Previously, the checkQuorum flag required an election timeout to
expire before a node could cast its first vote. This change permits
the node to cast a vote at any time when the leader is not known,
including immediately after startup.

Follower has already set its leader ID from

to be consistent, this adds a line to set its
leader id from leader snapshot message.

raft: fix comment,method name to needSnapshotAbort
...
And 'maybeSnapshotAbort' does not 'unset'
the pendingSnapshot. 'resetState', which is called after this
metho, is the one that unsets pendingSnapshot. So this changes
the method name.

raft: Call maybeCommit after removing a node.

removeNode reduces the required quorum size, so some pending entries may
