Description

When deleting a cluster that has pods with PDBs, I can not delete the whole cluster, since the nodes won't evict all of the workloads, causing the node groups draining step to fail.
Today, there is a flag when draining node groups of: --disable-eviction, which ignores PDB errors while draining the node groups.

I've added a flag: --disable-nodegroup-eviction, that will exist when deleting a cluster, and achieves the same behavior of the drain command with the --disable-eviction flag (it literally calls the drain function with the same value).

fixes #4416
