Trying to use the repl features before newly started nodes have
riak_repl completely initialized leads to all sorts of nasty crashes and
noise. Frequently it makes fullsync stuck forever, which makes a lot of
the tests fail.
This also tweaks the AAE fullsync tests to remove assumptions about
failure stats when AAE transient errors occur. The behavior in the
handling of those errors has changed recently with the introduction of
soft exits.
Verify that if the leader election occurs before the ring has converged,
that we still connect to remote sinks.
This test uses an intercept to ensure we can delay the ring events to
occur until after the election.
