Convert AllNodesExtraConfig to support composable roles
This adjusts the interface to OS::TripleO::AllNodesExtraConfig so
it supports custom/composable/optional roles.
Note this does break backwards compatibility, and I can't see any way
to avoid that. I've converted the in-tree templates, and we'll have
to document carefully and or provide a script (or automated conversion
via mistral perhaps?) to allow folks to easily adjust any out of tree
templates to the new format.
Basically you just have to:
1. Remove all the *_servers parameters, replace with one "servers"
json parameter
2. Replace references to e.g "controller_servers" with "servers, Controller"
which does a path-based lookup into the json map provided by overcloud.yaml
