TODO

• Handle signals like ctrl+c
• Use gorilla mux instead of net/http package
• Emit metric using prometheus go library ex: status_code{service_name=<>} 200
• Read json file containing list of endpoints to be tested
• Loop and make concurrent calls to test this endpoint. Wait for the results and send the results
