Add the required code and Dockerfile to build a Debian based container image of notificationservice-base to support v1 API backwards compatibility. The notificationservice-base-v1 code added here is being ported forward from stx.6.0. This code existed as-is in StarlingX prior to the work done to implement the ORAN Notification API. It is being returned in order to support user's needs for backwards compatbility. Subsequent work will done to update the helm charts, allowing notificationservice-base-v1-api and notificationservice-base-v2-api (ORAN Notification) to be deployed in parallel. Test plan: PASS: Build container image PASS: Manually deploy image and test with v1 client Story: 2010538 Task: 47175 Change-Id: I2f672fe1b226cb60b62bd5fe7f8abbedc7b0c4cc
