kubernetes: Try to kill pods when out of quota

Fixes a fairly recent issue where a restart could get stuck on the namespace quota. With this patch, when a quota error is detected during a restart the old pod will be killed which will free up quota for the new one to start.

There's still a possibility that something else will use that freed-up quota before the webservice pod can, but that should in theory be a rarer case than a tool that's just using all of their quota.

As a bonus, the timeout handling code is changed a bit so that Grid Engine webservices also get the "timed out, try manual stop and start?" message.
