[tests] address flakiness in raft_consensus_election-itest
Few test scenarios of the raft_consensus_election-itest suite
involving churny elections were showing flakiness when run in slow
mode with --stress_cpu_threads=16. The common root of the problem
was failing writer test thread due to timeout.
This patch addresses the issue, increasing Raft heartbeat interval
from 1 to 2 milliseconds. With this change, the above mentioned
tests become more stable, no longer failing due to the timeout error.
I ran the raft_consensus_election-itest built in DEBUG mode multiple
1K batches to confirm that.
Even with this patch, the above mentioned test scenarios sometimes fail
due to the DCHECK_GE assert in PeerMessageQueue::CheckMonotonicTerms().
The latter issues will be addressed separately.
