k8s: fix autodeploy

[P4sca1]

Autodeploy is no longer working in Kubernetes in recent shuffle versions.

findAppInfo leads to the following error:

Unable to list services: Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running? (may continue anyway?)

Replaced with deployApp again, which is working fine. Closes #1817

@0x0elliot verify this please. There's a lot of code changes in here that don't seem directly k8s related 🤔
