Convert ringbuilder to build devices array

Browse Source 
Currently we have some hard-coded mangling in t-h-t but we
instead need to build the array based on the nodes running swift
storage, combined with the SwiftRawDisks parameter.

This will enable running SwiftStorage on nodes other than Controller
and SwiftStorage roles, and is required for custom-roles due to
the hard-coded stuff in the role templates and overcloud.yaml
