1. Removed osh-infra-upgrade-host playbook from image building jobs,
as non-relevant
2. Removed osh-infra-deploy-docker playbook from image building jobs,
as docker-ce is deployed in run-image playbook
3. Removed osh-infra-build, osh-infra-deploy-k8s and security-bandit
playbooks - they are not referenced anywhere; bandit has already
been merged with pep8 job
