Subject: [PATCH] ktest: Add timeout for ssh sync testing
Git-commit: 4d00fc477a2ce8b6d2b09fb34ef9fe9918e7d434
Patch-mainline: v5.6-rc6
References: git-fixes

Before rebooting the box, a "ssh sync" is called to the test machine to see
if it is alive or not. But if the test machine is in a partial state, that
ssh may never actually finish, and the ktest test hangs.

Add a 10 second timeout to the sync test, which will fail after 10 seconds
and then cause the test to reboot the test machine.
