Fix for bugzilla #3700 - ARC1ClusterInfo.pm uses netstat
https://bugzilla.nordugrid.org/show_bug.cgi?id=3700
Description
Reimplementation of netstat/ss scan in HostInfo.pm
Logic for running the netstat/ss has moved to HostInfo.pm, with the addition of the ports hash in the schema.
New calls are added to CEInfo.pm.in to reference the ports and processes
ARC1ClusterInfo.pm has been heavily modified not to be dependent on netstat or ss. The information is only taken from HostInfo.pm datastructure.
