Description Alex McLeod 2019-11-12 15:11:48 UTC

Description of problem:

Presently there is no mechanism by which nodes which are being scaled-down / deleted can run any automated clean up; they simply get shutoff and removed from the pool.

Examples of house-keeping tasks that may be desired include:

Unsubscribing themselves from subscription manager, thus freeing resources.
Cleaning up service entries for compute nodes.

There is a desire for these functions and as such it would be helpful for work to be done to allow such hooks.
