Title:
  ConnectionError: ('Connection aborted.', BadStatusLine("''",))

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Description
  ===========
  Using python-novaclient, I call nova.servers.create() and then poll with nova.servers.get() until my new instance has a private IP assigned. Occasionally the client raises an error instead:

  ConnectionError: ('Connection aborted.', BadStatusLine("''",))

  I don't see any indication in the nova cloud controller logs as to
  what the failure may be.


  Steps to reproduce
  ==================
  * I used nova.servers.create() to create a server
  * I used nova.servers.get() to check if the new server was ready to use.
  * nova.servers.get() failed with an error:
  ConnectionError: ('Connection aborted.', BadStatusLine("''",))

  Expected result
  ===============
  I expected the server to come up in ACTIVE state and have a private IP assigned.

  Actual result
  =============
  The nova client throw a connection error.

  Environment
  ===========
  I'm running nova on newton:
