Support setting consolidation in karpenter-provisioner -lobur
What
This is an alternative way of deprovisioning - proactive one.
There is another way to configure Karpenter to deprovision nodes called Consolidation.
This mode is preferred for workloads such as microservices and is imcompatible with setting
up the ttlSecondsAfterEmpty . When set in consolidation mode Karpenter works to actively
reduce cluster cost by identifying when nodes can be removed as their workloads will run
on other nodes in the cluster and when nodes can be replaced with cheaper variants due
to a change in the workloads
Why
- To let users set a more aggressive deprovisioning strategy
