Subject: [PATCH 19/40] LuksScanner: Add LUKS dump scanner and models
Add LuksScanner actor that runs 'cryptsetup luksDump' for all 'crypt'
from lsblk output. The output is then parsed and filled into LuksDump
and LuksToken models.
The LuksDump model contains information about LUKS version, device UUID,
corresponding device path, name of the backing device (which contains
the LUKS header) and a list of LuksToken models.
LuksToken model represents a token associated with the given LUKS
device. It contains token ID, IDs of associated keyslot and token type.
If the token type is "clevis", we use "clevis luks list" command to
determine the clevis-specific subtype and append it to the token name.
E.g. if there is a "clevis" token and "clevis luks list" returns "tpm2",
the token type will be "clevis-tpm2".
