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.

We dont need expirer unless we have collector and standard
storage enabled. Lets turn it off by default and make it
an optional service. In upgrade scenario, we will kill the
process and stop the expirer, unless explicitly enabled.

Ceilometer collector is deprecated in Pike release.
Do not deploy by default. Instead use the pipeline
yaml to configure the publisher directly.

In the previous release[1], the services were stopped before the
pacemaker services, so that they get a chance to send last message to
the database/rabbitmq queue:
Let's do the upgrade in the same order.

We've broken the upgrade job because anyone upgrading with the
glance registry deployed (and defined in their *Services parameters)
will try to deploy with the old glance-registry.yaml defined in heat.
Instead we define a template which stops and disables the service on
upgrade.
