Add "knife serve" to serve up chef repo in chef-zero
Ensure server is stopped when knife is done
Depend on chef-zero 2.1, which has the right test hooks
React to fact that we bind chef-zero to localhost (not 127.*)
Explicitly add org defaults to pedant test
so that it passes, but don't feed the defaults to
the user by default.
Listen for the default port 8900, not 8889
Bump required revision of chef-zero to 2.1.3
Add knife serve to changelog / doc changes
Add more description to help for --repo-mode
Merge "knife serve" and chef-zero 2.1.3 improvements
