Especially on older hosts, we keep triggering errors::
ServerNotFoundError: Unable to find the server at
teuthology.front.sepia.ceph.com: [Errno 3] name does not exist
That comes from libevent's evdns via gevent.dns and httplib2. The rate
of these errors is low enough that they seem to be perhaps timeouts,
or more arbitrary. Busy looping on DNS resolution calls has never
triggered them, so far.
With ``monkey.patch_all(dns=False)``, the teuthology process will
block as a whole whenever doing DNS resolution. This will hopefully be
rare enough that it won't matter.
The only real "fix" seems to be upgrading libraries and hoping for the
best; this commit can be reverted after that is done.
