disk failure: test coverage for disk failure recovery

This patch adds an EMC test that spawns three servers and triggers EIOs
on two of them to fail two different tablets. With improper
disk-failure-handling, this scenario alone would have been enough to
leave the server with only a single copy of data, as the two servers
with EIOs would have been shut down entirely.

With proper disk-failure handling, this scenario would be salvageable,
and data would be replicated on the remaining disks. This exercises the
FlushMRS codepath.

Tests are also added to test behavior during FlushDMS calls and scans,
ensuring the servers return to a normal state.
