Implement the changePassword method

With this commit, it is now possible to change the password for the
LUKS-encrypted volume, using the changePassword D-Bus method for
eStoraged.

Tested:
$ busctl call xyz.openbmc_project.eStoraged \
  /xyz/openbmc_project/inventory/storage/mmcblk0 \
  xyz.openbmc_project.Inventory.Item.Volume FormatLuks ays 3 1 2 3 \
  xyz.openbmc_project.Inventory.Item.Volume.FilesystemType.ext4 \
  --timeout=60
$ busctl call xyz.openbmc_project.eStoraged \
  /xyz/openbmc_project/inventory/storage/mmcblk0 \
  xyz.openbmc_project.Inventory.Item.Volume ChangePassword \
  ayay 3 1 2 3 3 4 5 6
$ busctl call xyz.openbmc_project.eStoraged \
  /xyz/openbmc_project/inventory/storage/mmcblk0 \
  xyz.openbmc_project.Inventory.Item.Volume Lock
Attempted to unlock using the old password. It failed as expected.
$ busctl call xyz.openbmc_project.eStoraged \
  /xyz/openbmc_project/inventory/storage/mmcblk0 \
  xyz.openbmc_project.Inventory.Item.Volume Unlock ay 3 1 2 3
Unlocked with the new password
$ busctl call xyz.openbmc_project.eStoraged \
  /xyz/openbmc_project/inventory/storage/mmcblk0 \
  xyz.openbmc_project.Inventory.Item.Volume Unlock ay 3 4 5 6
