Enable docker image builds through buildkit directly #23030
Description
Is your feature request related to a problem? Please describe.
I need to run Docker image builds inside Kubernetes using buildctl for my actual job.
Describe the solution you'd like
I have an adhoc script for this today that basically mimics what Pants does for Docker builds today, except instead of docker build followed by docker push it just does buildctl build with --output type=image,name=...,push=true. I would like to build this logic into Pants itself.
