Add functionality to clone containers and volumes #9

The commit introduces a new feature that allows users to clone both containers and volumes. Functions have been added to facilitate the cloning process, including joomla__TRuST__clone, cloneContainer, and clonePersistentVolume. Adjustments have also been made in the main program to include this new cloning option into the interactive menu.
