Use qemu-kvm-ev package on centos

Browse Source 
For the latest qemu-kvm, you have to use the qemu-kvm-ev package,
which is based off the qemu-kvm-rhev package, which is explained in
[1] but you probably can't read it.  The gist is, that qemu-kvm-rhev
is a later build of kvm that is incompatible with the base version
provided.  qemu-kvm-rhev is only provided with the RHV (ovirt) and
RHOS (openstack) products.  CentOS rebuilds this package as
qemu-kvm-ev as part of it's virtualisation SIG.

I9a972e3fde2e4e552f6fc98350820c07873c3de3 has bumped up the minimum
qemu version to 2.1.0.  It seems there is a an issue (bug #1668164)
where having the qemu-system package installed gets picked up if
installed, and reports the incorrect version to nova, causing failure.

This removes the installs from files/rpms/nova as it is all being done
in function-libvirt.  We only install the qemu-kvm-ev package on
centos and remove the old work-around.
