Add docker and deployment scripts for exemplar video streaming microservice

JIRA: CLOVER-72

This issue falls under the "Edge Cloud-Native Cluster" intern project and is a part of both Clover and Edge cloud projects. The scripts added are of an exemplar video streaming microservice designed to run on the raspberry pi edge cluster. This commit includes the docker scripts to containerize the UV4L stream and the kubernetes deployment script to correctly run the microservice as a pod on the cluster. The detailed description of the project and the instructions for using the scripts are documented in the README.
