[Feature]: Validate new k0-built images, decommission docker builds to complete migration

[mchmarny]

Prerequisites

• I searched existing issues

Feature Summary

Only health-monitors/syslog-health-monitor and health-monitors/gpu-health-monitor continue being built by Docker, everything else that's pure Go based migrates to ko-built images

Problem/Use Case

Until the new ko-built images are validated we are building concurrently in ko and docker.

Proposed Solution

We can remove the maintenance overhead, benefit from smaller and more secure images at runtime, and shorten our tests by removing the duplicate Docker builds for the images that are built by ko

Component
