This commit removes the need for datatypes.JSON and makes the code a bit
cleaner by allowing us to use proper types throughout the code when it
comes to hostinfo and other datatypes on the machine object.
This allows us to remove alot of unmarshal/marshal operations and remove
a lot of obsolete error checks.
This following commits will clean away a lot of untyped data and
uneccessary error checks.
