Markus Hentsch 2b42257eff Add get_passphrase_from_secret utility function
This function outsources Cinder's encryption passphrase handling based
on Key Manager secrets. It extends Cinder's existing implementation to
handle secret objects of type 'passphrase' additionally, for which the
binascii.hexlify conversion is now skipped similar to Nova's
implementation of handling qcow2+LUKS images. Original Cinder behavior
for 'symmetric' secret objects is retained.
Provides the basis for image encryption standardization as per
https://specs.openstack.org/openstack/cinder-specs/specs/2024.2/LUKS-image-encryption.html
