[2.0.2 RN + Manual?]Host name and IP address management in Couchbase

• Need ability to use host names that don't revert to IPs
• Need ability to non-disruptively change the IP address of nodes
• When setting up hostname based cluster(using etc/hosts), nodes revert back to ip when a new node is added by Hostname.

From logs:

Decided to change address to "<IP>"

Steps followed:
1.) Install 2.0 GA
2.) Stop couchbase-server
3.) Add ns_name to couchbase-server
4.) remove files per:http://www.couchbase.com/docs/couchbase-manual-2.0/couchbase-bestpractice-cloud-ip.html
5.) add hostname to /opt/couchbase/var/lib/couchbase/ip
6.) Start server and configure with beer-sample
7.) Hostname shows up correctly
8.) Add new node by hostname(no need to rebalance)
