mon/Elector: do a trivial write on every election cycle

Currently we already do a small write when the *first* election in
a round happens (to update the election epoch).  If the backend
happens to fail while we are already in the midst of elections,
however, we may continue to call elections without verifying we
are still writeable.

mon/MonitorDBStore: assert/crash if there is a write error

check the error code.  There are no cases where we want to
tolerate a commit failure.
