CapacityBuffer is the configuration that an autoscaler can use to provision buffer capacity within a cluster.
This buffer is represented by placeholder pods that trigger the Cluster Autoscaler to scale up nodes in advance,
ensuring that there is always spare capacity available to handle sudden workload spikes or to speed up scaling events.

Limits, if specified, will limit the number of chunks created for this buffer

limitations for the number of chunks (i.e., `replicas` or `percentage` are not set),
this will be used to create as many chunks as fit into these limits.
type: object
percentage:
description: |-
Percentage defines the desired buffer capacity as a percentage of the
`scalableRef`'s current replicas. This is only applicable if `scalableRef` is set.
The absolute number of replicas is calculated from the percentage by rounding up to a minimum of 1.
For example, if `scalableRef` has 10 replicas and `percentage` is 20, 2 buffer chunks will be created.
