Format LUKS encrypted device

This commit adds the functionality to format a new LUKS device, create a
filesystem, and mount it. Unit tests are included.

Currently, the D-Bus interface to format the LUKS device is synchronous,
but it may need to become asynchronous, since it can take some time. The
format operation took about 20 seconds when testing it.

Tested: Ran eStoraged on a machine with an eMMC, using the following
commands:
$ /usr/bin/eStoraged -b /dev/mmcblk0 &
$ busctl call xyz.openbmc_project.eStoraged.mmcblk0 \
  /xyz/openbmc_project/storage/mmcblk0 xyz.openbmc_project.eStoraged \
  Format ay 3 1 2 3
$ busctl call xyz.openbmc_project.eStoraged.mmcblk0 \
  /xyz/openbmc_project/storage/mmcblk0 xyz.openbmc_project.eStoraged \
  Lock ay 3 1 2 3
$ busctl call xyz.openbmc_project.eStoraged.mmcblk0 \
  /xyz/openbmc_project/storage/mmcblk0 xyz.openbmc_project.eStoraged \
  Unlock ay 3 1 2 3
