Description

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.
