Hi,

the Heat/Puppet implementation of the Overcloud deployment seems to be 
surpassing in features the Heat/Elements implementation.

The changes for Ceph are an example, the Puppet based version is already 
adding features which don't have they counterpart into Elements based.

Recently we started working on the addition of Pacemaker into the 
Overcloud, to monitor the services and provide a number of 'auto 
healing' features, and again this is happening in the Puppet 
implementation only (at least for now) so I think the gap will become 
bigger.

Given we support different implementations with a single top-level 
template [1], to keep other templates valid we're forced to propagate 
the params into the Elements based templates as well, even though there 
is no use for these there, see for example [2].

The extra work itself is not of great concern but I wonder if it 
wouldn't make sense to deprecate the Elements based templates at this 
point, instead of keep adding there unused parts? Thoughts?
