Improve systemd service units

[yersan]

Description

At this moment, WildFly is shipped with a set of minimal Systemd units under docs/contrib folder. See https://github.com/wildfly/wildfly-core/tree/main/core-feature-pack/common/src/main/resources/content/docs/contrib/scripts

These files are user contributions with basic capabilities and are there as examples and/or reference.

This feature aims to allow users to configure and install a server installation as a Systemd service either for standalone and domain mode using Systemd units developed and maintained by the WildFly team and its community instead of just pure community-contributed scripts only.
