QA/TestCases/LUKS Encrypted RAID partitions, some mds encrypted

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 functionality should continue to work as expected, and not create situations where the encryption leads to undesired errors.

Steps To Reproduce

• start the installer
• enter the disk druid paritioning screen
• Create multiple new RAID partitions
• select the "encrypt" checkbox for each partition
• enter a passphrase for the partition
• create one or more encrypted md devices using the RAID partitions
• select the "encrypt" checkbox for each filesystem that is composed of RAID partitions
• create one or more non-encrypted md devices using the RAID partitions
• continue the installation

Expected Results

in post-install system, verify:

• a passphrase for each RAID partition is required to access it
• an entry for each RAID partition exists in /etc/crypttab
• a passphrase for each of the encrypted filesystems using the RAID partitions is required to access it
• an entry for the block devices and filesystems using the RAID partitions exist in /etc/crypttab
