> We need a script or hacky solution internally for base-cluster to be able to 
> delete old HDP stacks.
> This does not need to be a full-blown feature with tons of bells and whistles 
> and UI support.
> Instead, it needs to be a simple script that can be ran on all hosts.
> Ideally, it would accept the version of the stack to remove, and perhaps can 
> go into contrib.
> If we want to make it slightly better, than we can figure out how to actually 
> make it a custom command to remove older versions (value is less than the 
> CURRENT version).
> If done this way, we can add checks to make it more robust, bubble up errors 
> to the UI task output, etc.
