Email and SMTP hardcoded in publisher scripts

[mschoettle]

Various publisher (Perl) scripts have functionality to inform of a potentially hanging script.

The from, to, and SMTP host are all hardcoded.

See for example:

opal-admin-legacy/publisher/controls/announcementControl.pl

Lines 105 to 115 in 5bbd836

	# email error
	my $mime = MIME::Lite->new(
	'From' => "opal\@muhc.mcgill.ca",
	'To' => "gregormitchell\@gmail.com",
	# 'Cc' => "someone\@gmail.com",
	'Subject' => "Potential hanging script - Opal announcementControl.pl",
	'Type' => 'text/html',
	'Data' => \@logs,
	);
	my $response = $mime->send('smtp', '172.25.123.208');

This either needs to be configurable, or, since all scripts that run periodically are executed via Ofelia (which takes care of sending an email if a script fails), we remove this functionality completely.

I am tending to the latter option.
