[improvement]: Allow customization of Asterisk start/stop commands

[JoseGoncalves]

FreePBX Version

FreePBX 17

Improvement Description

If someone builds/packs it's own Asterisk, or uses some pre-built Asterisk packages (like the ones provided by Debian), it will most probably have a systemd service file that he can use to start/stop Asterisk.

In those situations, it will be a nice addition if someone that starts/stops Asterisk via fwconsole start/stop/restart commands will downwards cause the invocation of systemctl start/stop/restart asterisk.service commands.

I've successfully tested using systemctl to start/stop Asterisk in my system with these patches to FreePBX libraries:

My suggestion would be to add a config variable to /etc/freepbx.conf that would control which commands are used to start/stop Asterisk gracefully.

By default, the old behaviour of stopping with asterisk -rx "core stop gracefully" and starting with safe_asterisk would be used.

When that new config variable was set to a value that would cause the usage of the new start/stop commands, systemctl would be used to start/stop Asterisk.
