feat(db): support using postgresql service connection file
Add new service rdbms config option to set the service name to be used
with a postgresql service connection file.
This can be done using the PGSERVICE environment variable for a single
instance tracker server. For a multi-instance server this per-tracker
config option is needed.
Note that settings (host, user, (db)name...) in config.ini file will
override the service connection file setting. Also setting PGSERVICE
and service will use the service setting.
