bb/command|cooker: refactor the reparseFiles logic

Turn the reparseFiles logic into a command to reset the cooker's state
machine and a noop which triggers a cache rebuild.

The resetCooker command resets the cookers state machine such that a cache
update will be triggered by any async command which requires the cache.
The reparseFiles command remains as a noop async command that has the
needcache property set to True so that when called it ensures the cache is
built.

Patch from Richard with the addition of removing the force parameter from
the updateCache method.
