UniquePodNames enabler

Greenfield unibeta/gamma deployment OSP18 uses uniquePodNames by default. In
contrast, the adoption unigamma job doesn't use it yet. This creates a
descrepency between adoption job and clean unibeta/gamma deployment jobs. This
patch creates an enabler without changing a default behavior. Unigamma adoption
job will be changed accordingly
