Added option -r <pidfile> for resmon. If none provided it will run without creating pidfile. If provided, it will try write it's pid into specified file. Resmon-systemd.service should have this file as an argument for resmon as a PIDFile option and in ExecStart option.

Could fix style (spaces around operators and commas) if that matters.
Not sure about convention here, but maybe lowercase the $PIDFILE var so it doesn't look like the file handle PIDFILE, or just keep using $config->{pidfile}.

Please use the three-arg form of open(), instead of the two-arg form with string interpolation, and scalar filehandles instead of barewords:
open(my $pidfh, '>', $config->{pidfile}) or die "can't open $config->{pidfile}";

Thanks, updated pull request. |
'==' can not compare file handles. We can use fileno() function to compare numerically file numbers. Code without this returns "connection successful" when it timeouts and $fd is "undefined".

Typo fixed, thanks to @yakatz. Fixed excessive restarting of the unit and provided PIDFile for systemd.
