- use statefulsets instead of deployments for mongo, redis, signer - use k8s job + statefulset for running crawls - use separate statefulset for crawl (scaled) and single-replica redis stateful set - move crawl job update login to crawl_updater - remove shared redis chart package refactor: - move to shared code to 'btrixcloud' - move k8s to 'btrixcloud.k8s' - move docker to 'btrixcloud.docker'
