freebsd init: added new functionality and enabled better logging (#1740)

Browse Source 
* uses more of the builtin functionality for starting and stopping of the process by using command and command_args along with procname
* removed -f from daemon as this was hiding error message that were sent to stdout on startup, now writing stdout to the logfile directly

for example, this was being hidden:

“Activating privacy features.. [www.domain.com] failed to get certificate: Error presenting token: Could not find the start of authority”

it now shows up in the log

* aded “caddy_env” to allow the setting of environment variables that caddy might need, for example when setting creds for “DNS Challenge”

* added a check to ensure caddy_config_path file exists
