Androz2091

Open a PR in Androz2091/k8s-infrastructure that bumps a Deployment's image tag to the SHA of the latest successful Docker build for the current repo. Use when the user wants to deploy a freshly-pushed change ("bump the image", "open a PR to k8s-infra", "deploy the latest", "ship this to prod"). Polls until the CI build succeeds, finds the manifest via grep, opens a PR but does NOT merge it.
