Subject: timeout 120 teuthology-killl is highly recommended

Hi Ceph,
Today I did something wrong and that blocked the lab for a good half hour.
a) I ran two teuthology-kill simultaneously and that makes them deadlock each other
b) I let them run unattended only to come back to the terminal 30 minutes later and see them stuck.
Sure, two teuthology-kill simultaneously should not deadlock and that needs to be fixed. But the easy workaround to avoid that trouble is to just not let it run forever. Even for ~200 jobs it takes at most a minute or two. And if it takes longer it probably means another teuthology-kill competes and it should be interrupted and restarted later. From now on I'll do
timeout 120 teuthology-kill .... || echo FAIL!
as a generic safeguard.
Apologies for the troubles.
