Commit Message

Terminate exporter process if maximum open files exceeded

This is somewhat of a workaround for the exporter becoming
perpetually blocked when it runs out of file descriptors if
the cluster is down for too long, as mentioned in:

  https://github.com/digitalocean/ceph_exporter/issues/60#issuecomment-319396108

The problem is that if the MONs are down for long enough,
each time prometheus scrapes the metrics, another socket is
opened, but these block forever.  If the cluster comes back
up before we run out of FDs, the blocked requests recover.
If the clusetr *doesn't* come back up before we run out of
FDs, the blocked requests never recover.

This commit causes ceph exporter to terminate if it runs
out of file descriptors, which IMO is better than blocking
forever -- it'll be a noisier failure, and also if you're
running ceph_exporter via systemd, systemd will then
automatically trigger a service restart.
