Create a liveliness endpoint for all apps

[raisedadead]

All the apps need to start with a base template, which should have a default liveliness check endpoint for deployments.

For instance, every app should implement a /status/ping, and that should return an HTTP error code of 200 with a response of { "msg" : "pong" }

This issue may be split into multiple PRs, with one PR for every project.
