Lubomír Sedlář 129e654690 Compute checksums in ImageChecksumPhase
The phase goes through all images declared in image manifest, computes
their checksums, stores them in appropriate files and updates the
manifest so that it includes the actual checksums.

The documentation contains details about new configuration options.

The test suite now needs Python's mock package.
