Simple Healthcheck Implementation (Docker)

[michael1800v1]

Specifically for the docker image, please consider a simple, unauthenticated healthcheck api and include wget or curl, or a node command that can be called periodically to return a 0 or 1 exit code.

I absolutely love the basic nature of DumbPad and do not want to bloat or complicate it, however, a healthcheck is needed to allow Docker Swarm or K8 to detect failures, and move between nodes automatically for maintenance, backups, hardware failures, etc. Low priority but would be appreciated.

I'll look at rolling this our for the whole DumbSuite
