tools/test_reconnect.sh may not be able to finish

the tools/test_reconnect.sh test can get itself stuck by restarting too fast, which can result in
the test never finishing. If we send enough IO when a downstairs is off, the upstairs will kick it
out and require LiveRepair. This results in things taking longer before that downstairs is back
to Active. If another downstairs goes away during this, then that means it will take even longer
before everything is back to normal.

This test was a test for the replay functionality, and in its current form it may not be able to
test that.

There is now a crutest replay option that does what we need, so this test (test_reconnect.sh)
should probably be abandoned and a new test developed.
