Osier Yang bc4e5b43c2 storage: Wait udev events are handled before removing lvm vol 
Related #BZ: https://bugzilla.redhat.com/show_bug.cgi?id=702260.

There are two problems described in the BZ:
1) "Can't remove open logical volume".
2) "Unable to deactivate logical volume "foo""

This patch just intends to fix 2), as 1) is expected if the vol
is still used by something, and you never known if "lvchange -an"
will fail or not either (sometime, it will succeed, sometimes not).
We'd better not look for trouble, :-)

For 2), that's caused by race between lvremove and udev event handling,
the only workable way now is to wait the events handling are finished,
though it might introduce latencies, as "udevadmin settle" exits
after *all* events are handled, it's the only way we can fix
the racing in libvirt layer.

See https://bugzilla.redhat.com/show_bug.cgi?id=570359 for more
details.

         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.
