These addresses are given defaults of 0.0.0.0 in the role defaults
but in a deployment we know which address each service should bind to.
The variable container_address should hold the local mgmt network IP
address for either containerised or metal deployments.
This patch defines a new variable management_address which removes
confusion about container_address for metal deployments, and overrides
the role default bind addresses for all roles.
