[autotest] Add a 'repair_hosts' command.
We have a `reverify_hosts` command for triggering Verify tasks, but
nothing for triggering Repair tasks. So, add the command.
BUG=chromium:754362
TEST=Run against a couple of working, idle DUTs in the lab

+# Simple utility to trigger a Repair job on a bunch of hosts.
+#
+# CAVEAT: no error checking; if any argument isn't a valid
+# host, it will be silently ignored. If there are no command
+# line arguments, silently succeed.

+# For simplicity, we want to do nothing if there are no hosts named
+# on the command line. That makes it easy to do stuff like this:
+# dut-status -b $BOARD -p bvt -n | xargs repair_hosts
+#
+# By doing nothing, we get more useful behavior if all the DUTs selected
+# by `dut-status` are actually working.
+#
+# Note that we have to specifically test for an empty host list: I
+# _think_ (but I don't know) that the AFE calls operate on all the
+# hosts if there are no arguments given. I do know for certain that
+# with hostnames=[], the call takes longer than I was willing to
+# wait.
