Adding pipeline for container scan / fix some vulnerabilities

Some vulnerabilities are not fixed yet. We need more support to get them fixed, this is a direct report of the vulnerabilities but most of the items listed are part of the airflow/debian subsystem, therefore we cannot get rid of those I filled out the vulnerability-allowlist.yml file which contains the vulnerabilities to be allowed. Refactor pipeline to use template for container scan. Related to osdu/platform/deployment-and-operations/infra-azure-provisioning#216 (closed)
