bash_completion script for Chef's knife command.
Enables tab completion on some of the common knife commands.
Caches some data to avoid querying the server each time.
Assuming bash-completion is installed this script can be installed as /etc/bash_completion.d/knife and made available immediately by using '. /etc/bash_completion.d/knife'
Tested with Knife version "Chef: 11.12.2"
