Also added option --snapshot-descr DESCR to allow users to add a description when creating a snapshot.  Currently, the descripton field is hardcode to an empty string.

* fixed 11 violations identified by Hound

* Refactored display_node method to output snapshot tree hierarchy in json and various other formats. Also added snapshot description to the snapshot info that is outputted.

* fix issues identified by hound

* fix more changes identified by hound

* Fix code to use map when listing snapshots. Removed the shift statement in display_node method as it is no longer required as we are now storing the list of snapshots in a data structure.
