Subject: [PATCH 10/10] templates: import /etc/crypttab to grub.cfg

The /etc/crypptab is used to setup location of encryption key files during
boot, among other things. It is useful to make use the information by grub to
determine where keys are being looked up.

This script can be used to import relevant /etc/crypptab entry to grub.cfg.
