QA/TestCases/LUKS Partition Probing (previous install)

Description
Support the use of encrypted filesystems for anything other than /boot using cryptsetup and LUKS. This includes install time creation/configuration, as well as integrated support in mkinitrd and initscripts (others?). Currently we are only pursuing support for encrypted devices using cryptsetup/LUKS.

When using encrypted file systems/block devices, the rescue mode functionality should continue to work as expected, and not create situations where the encryption leads to undesired errors; in particular, a user should be able to successfully enter rescue mode for a system that has its root fs on an encrypted block device.

Steps To Reproduce
Set up the system that uses one or more of each kind of encryption: Then start the installer and test:
 * encrypted block devices
 * encrypted filesystems
 * Boot anaconda
 * Proceed to the partitioning dialog
 * Each of the encrypted block devices are correctly identified by anaconda, and require passphrase to access
 * Each of the encrypted file systems are correctly identified by anaconda, and require passphrase to access

Expected Results

 * Verify each of the encrypted block devices are correctly identified by anaconda, and require passphrase to access
 * Verify each of the encrypted file systems are correctly identified by anaconda, and require passphrase to access
