Title: Healthcheck routes for monitoring.

/ping - 200 with plain text "OK"
/status - 200 with json server uptime info

Status can of course return different information, such as memory use or the status of connections to other required resources. The intent is that /ping is extremely low cost, so it can be hit constantly, and /status can expend slightly more resources.
