Add clean shutdown flag and checksum to the published metadata

The shutdown flag is published only when the agent shuts down
cleanly and the checksum (crc32) is used to protect the metadata
section from corruption.

Both features will be then used together with sanlock lease file
to make sure a host can be decommisioned.
