sh: Add a new "cros_payload" to manage resources for installers.

For better managing how factory resource will be installed, we need an
unified system for different installation scenario (RMA-USB,
Shim/Network(Omaha), Netboot, Copy-Machine, ...).

The new 'cros_payload' defined a new way to keep storage for
installation of disk and file resources.

To use this:

 1. Create a JSON config file with only '{}' in resources folder.
 2. cros_payload add board.json firmware ~/Downloads/chromeos-firmwareupdate
 3. cros_payload add board.json release_image ~/Downloads/*recovery*.bin
 4. cros_payload add board.json test_image ~/Downloads/*test_image*.bin

Check board.json which should have reference to gzipped contents.

 5. Get a empty USB stick, say /dev/sde, and format properly:
 6. cros_payload install board.json /dev/sde release_image
 7. cros_payload install board.json /dev/sde test_image

Performance (tested on z840):
