Convert ringbuilder to build devices array
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 Change-Id: I11deed1df712ecccf85d36a75b3bd2e9d226af36 Partially-Implements: blueprint custom-roles
