Title:
  GET on os-networks/<uuid> fails with quantum

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  This is  because of NULL host column in network table and here's the
  stack trace:

  ------------------------------------------------

  Now I can think of two options:

   1. remove the NULL sanity check in network_get_all_by_uuids (nova.db.sqlalchemy.api)
   2. QuantumManager puts dummy recode in host column
