Server returning cached data

An example of how to implement a server that caches data

Goals:

• The cache has a TTL
• Each request must be handled as fast as possible, while returning a fully valid response
• Consider the updateCache function as expensive, so must avoid unnecessary calls.
• Don't block startup (assume the application does other stuff and that must be up asap)
• Be correct (no data races)
