Kaniko and volume mounts for cache

[nethi]

Hi, I am running kaniko builds in k8s container. In devspace.yaml, how can we add volume mounts for pre-warmed base images, as described here https://github.com/GoogleContainerTools/kaniko/blob/main/examples/kaniko-warmer.yaml

Devspace documentation talks about only secrets and configmap mounting.
