This adds support for a GPT label type to the partitioning code. This is relatively straight-forward translation of the partition config into a sgparted command-line and subsequent call. A unit test is added based on a working GPT/EFI configuration and the fedora-minimal functional test is updated to build a single-partition GPT based using the new block-device-gpt override element. See notes in the sample configuration files about partition requirements and types. Documentation has been updated.
