Cole Robinson 441e881e9a nwfilter: Save config to disk if we generated a UUID 
libvirt-daemon-config-nwfilter will put a bunch of xml configs
into /etc/libvirt/nwfilter. These configs don't hardcode a UUID
and depends on libvirt to generate one. However the generated UUID
is never saved to disk, unless the user manually calls Define.

This makes daemon reload quite noisy with many errors like:

error : virNWFilterObjAssignDef:3101 : operation failed: filter 'allow-incoming-ipv4' already exists with uuid 50def3b5-48d6-46a3-b005-cc22df4e5c5c

Because a new UUID is generated every time the config is read from
disk, so libvirt constantly thinks it's finding a new nwfilter.

Detect if we generated a UUID when the config file is loaded; if so,
resave the new contents to disk to ensure the UUID is persisteny.

This is similar to what was done in commit a47ae7c0 with virtual
networks and generated MAC addresses

         LibVirt : simple API for virtualization

  Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
