make region creation dynamic & remove external dependency

[jmarhee]

move facility var to list; spin up module instance for each in list.

in 0.12, for syntax is supported, but external data is not, if this data could be handled by remote-exec then we can remove external provider dependency and then foreach the facilities list

7 addresses this (removes external dependency for cluster name, still need it for node-token)
