Extend postgresql service definition

[p-j-smith]

Fixes #10

Requires #12 to be merged first (as that pr updates the ansible-lint pre-commit hook)

• define a variable postgresql_service.directory for extending the service configuration, defaults to:

"/etc/systemd/system/{{ postgresql_service_name }}.service.d"

• update the default postgresql_service.filename:

filename: "/etc/systemd/system/{{ postgresql_service_name }}.service.d/postgresql_service.conf"

• add a task to ensure postgresql_service.directory exists
• remove the .include command from the pg_hba.conf.j2 template

Looks good!

Just a thought, perhaps we could add renovate to this repo to track pre-commit hook versions? And perhaps versions in requirements.txt (unless we pin as they are for just for molecule)?
