Rework btrfs handling (#1234)

* Restructuring btrfs.py into lib/btrfs/*.py

* Reworking how BTRFS subvolumes get represented, and worked with. Subvolumes are now their own entity which can be used to access it's information, parents or mount location.

* Added BtrfsSubvolume.partition and other stuff.

* Reworking the way luks2().unlock and .format() returns device instances. They should now return BTRFSSubvolume where appropriate.

* Fixed a missing import

* Fixed an issue where mkfs.btrfs wouldn't trigger due to busy disk.

* Fixing subvol mounting without creating a fake instance.

* Added creation of mountpint for btrfs subvolume

* Fixed root detection

* Re-worked mounting into a queue system using frozen mounting calls using lambda

* Removed old mount_subvolume() function

* Removed get_subvolumes_from_findmnt()

* Fixed Partition().subvolumes iteration

* Adding .root to BtrfsSubvolume

* Fixed issue in SysCommandWorker where log output would break and crash execution due to cmd being a string vs list

* Changed return-value from MapperDev.mountpoint to pathlib.Path
