Vladimir Kozhukalov b86f4b1462 Rename package to fuel-target-centos-images6.6
To support several Centos versions we need
both Centos6.5 and Centos6.6 images to be
in place. But during master node upgrade
we update fuel-target-centos-images package
and Centos6.5 images disappear. The case is
the same as for fuel-library.
