When a service is enabled on multiple roles, the parameters for the
service will be global. This change enables an option to provide
role specific parameter to services and other templates.
Two new parameters - RoleName and RoleParameters, are added to the
service template. RoleName provides the role name of on which the
current instance of the service is being applied on. RoleParameters
provides the list of parameters which are configured specific to the
role in the environment file, like below:
parameters_default:
# Default value for applied to all roles
NovaReservedHostMemory: 2048
ComputeDpdkParameters:
# Applied only to ComputeDpdk role
NovaReservedHostMemory: 4096
In above sample, the cluster contains 2 roles - Compute, ComputeDpdk.
The values of ComputeDpdkParameters will be passed on to the templates
as RoleParameters while creating the stack for ComputeDpdk role. The
parameter which supports role specific configuration, should find the
parameter first in in the RoleParameters list, if not found, then the
default (for all roles) should be used.

This profile will request the certificates for the services on the node.
So with this, we will remove the requesting of these certs on the
services' profiles themselves.
The reasoning for this is that for a containerized environment, the
containers won't have credentials to the CA while the baremetal node
does. So, with this, we will have this profile that still gets executed
in the baremetal nodes, and we can subsequently pass the requested
certificates by bind-mounting them on the containers. On the other hand,
this approach still works well for the TLS-everywhere case when the
services are running on baremetal.
