ovsdb raft: Support leader election time change online.
A new unixctl command cluster/change-election-timer is implemented to
change leader election timeout base value according to the scale needs.
The change takes effect upon consensus of the cluster, implemented through
the append-request RPC. A new field "election-timer" is added to raft log
entry for this purpose.
