add9e5da58
This is a foundation for CLI work, still has rough spots but works for two PoC commands - rack-list and rack-show (communicates with Tuskar, prints). There's remaining stuff to be solved: * Allow arbitrary formatting of attributes (bug #1213056) * Add help support for subcommands (bug #1213050) * Allow finding resources by name (bug #1213053) * Allow auth with pre-existing token and Keystone URL (bug #1213052) Fixes bug #1211826 Change-Id: I9364be37c7111c85ef46be82b157782a14743004
