DISK: Add SET NOAUTOSIZE - disable autosize when attaching existing containers

Browse Source 
This is a global command possibly for folks who have configurations which
always explicitly specify the drive type they want a particular unit to be
before they attach a container to the unit.  The side effect of this will
be to avoid the addition of drive type describing meta data to disk
containers.
