reclass: maas: Dynamic machine definitions

Refactor maas machine definition flow from going through variables
in pod_config.yaml to directly handling it in Fuel using a new j2
template.
This prepares for future improvements allowing a dynamic compute
node count, as well as parameterizing new values via j2.

For now, node roles and count are still statically mapped to PDF
nodes.

JIRA: FUEL-319
