Support encrypting multiple partitions (#759)

* Added support for storing disk encryption keyfiles and add them to a keyslot.
* Added a luks2().add_key() function in order to inject a keyfile into a keyslot on a encrypted volume.
* Simplified 'missing encryption password' logic in Filesystem(). Added a call to luks2().add_key() after the root-password is set on the volume, to add the keyfile in slot 2
* Adding in password handling in luks2().add_key(). It's required to enter a previous passphrase to unlock the volume and add a new keyslot. Also simplified the handling of partition in Installer().mount_ordered_layout()
* Adding in encryption on all partitions except /boot when encryption is opted in
* Removed setting size on Partition() as it's a read only value. No idea how Partition().size = size hasn't caused an issue before. Removed size=X argument to Partition()
* Added a uniqueness to the loopdevice name. This should ensure that multiple encrypted volumes can be opened at the same time, except for Partition().detect_inner_filesystem() operations which can only happen one at a time since they share namespace. This should never be an issue since archinstall is single threaded and no concurrent operations can/should happen.
* Added partprobe() as part of disk/helpers.py, added a /dev/ -> UUID mapper function called convert_device_to_uuid(path). Added a luks2().crypttab() function that sets up a /etc/crypttab entry.
* Moved the responsability for telling archinstall to generate a keyfile from Filesystem() to user_interaction.py. This should in the future be a user-input based value, and not something the Filesystem() automatically dictates.
* Added a retry mechanism to luks2().encrypt() to avoid having to re-start the installation when a device simply wasn't up yet.
* Swapping UUID= lookup from loopdev to physdev.
