Subject [67/85] [abbrv] incubator-asterixdb-hyracks git commit: Add ability to configure network ports for NCs and CC.
Date Fri, 24 Apr 2015 18:46:34 GMT
Add ability to configure network ports for NCs and CC.

This includes the ability to specify different "public" ports, for situations
when a node is behind a NAT firewall.
Also eliminate IP check for data and dataset network addresses, which
should allow DNS names to be used as well.
Some internal cleanup regarding handling network addresses.
