Extend the tripleo client Command class to fetch heat roles data
from a role file. That new class method is shared by many derived
classes afterwards and used for containers images preparations,
containerized overcloud, undercloud and standalone deployments.
Apply normalization to the roles_file in plan management and
preflight checks as well.
