Subvolume User Interface (#1032)

* Deflate the user interactions file

* Fix flake8

* GlobalMenu split from selection_menu.py

* Upgrades to ListManager:
Can now show an empty list if there is no null action.
More information to the user at the header

* Put only_hd.py  and swiss.py to use new config printing mechanism
Solved a couple of bugs at
ListManager adding a str and a DeferredTranslation
ManageUser was missing an self argument in _check ...

* Create list and menus to manage subvolumes in btrfs partitions
Needed to modify manage_new_and_existing_partitions
Added a new parameter filter to select_partition, to allow filtering there

* Update internationalization strings
