Blaine Gardner 50e824ebad Ceph: Add unit tests for nfs-ganesha spec
Ganesha isn't a true "Ceph" daemon, so some of the sharable pod spec
testing functionality is teased out of the operator/ceph/test library
and a simple operator/test library is created. The ceph/test library is
updated to use the operator/test library when possible/appropriate.
