Refactor healthcheck-k8s.py
Error reporting was improved by returning actual error message from subprocess call to 'kubectl' command. Code readability was improved by defining a dictionary of endpoint names to check and their IPs. Unsecure 'shell=True' property in Popen constructor for kubectl command in SDNC DB was removed and command string itself sanitized. Overall code readability was improved by reusing common commands in a loop.
