Clark Boylan 06b7352478 Fix async race updating nova configs ...

The configure_neutron_nova function updates nova configs. While that is
still running we separately update nova configs in stack.sh. This can
result in unexpected configs (that don't work). Fix this by waiting for
configure_neutron_nova to complete its work before we do nova config
updates directly in stack.sh.

For specifics we say that:

  [neutron]
  project_domain_name = Default

was missing from both nova.conf and nova-cpu.conf and instances could
not be created because keystone complained about not finding domain in
project. The strong suspicion here is that on some systems
configure_neutron_nova would write out project_domain_name while the
stack.sh inisets were running resulting in stack.sh overwriting the
project_domain_name content.

One theory is that disabling swift makes this problem more likely as
there is swift work in the middle of the async period. This is supported
by the fact that our job that hits this problem does indeed disable
swift.
