Configure DB addresses for each service

Browse Source 
To enable partitioning of DB traffic by-service, each service needs to
use a custom connection string. Defaulting the service address to a
common galera_address makes things continue to work by default.

While the galera_address could be overridden on a container or host
basis this requires repeating that behavior across each infra node in
the inventory. Providing service-specific connection address variables
simplifies the management somewhat for large deployments and may reduce
error rates.

The service install playbooks now default the service-specific variables
instead of galera_address to the internal lb vip from inventory to
maintain the ease-of-use currently available.

Any value for a service-specific variable set in user_variables.yml will
override the value in the playbook's vars to provide selective
customization as needed.
