Configure DB addresses for each service
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.
