LU-14359 hsm: support a flatter HSM archive format

LU-14359 hsm: support a flatter HSM archive format

Add versioning (v1 and v2) to the HSM archive format (directory
layout):
  v1: (oid & 0xffff)/-/-/-/-/-/FID
  v2: ((oid ^ seq) & 0xffff)/FID

v1 is the original layout and the default. v2 is the new layout which
should be selected for new installs.

Add an option --archive-format to select the archive format.

Add YAML configuration file support to lhsmtool_posix with properties
achive_format and archive_path. Add an option --config to set the
config file.

Adapt sanity-hsm and test-framework to allow testing of both archive
formats.
