Server example that talks to Redis

[mzimbres]

Can you please provide a HTTP server example that

1. Accepts a HTTP POST with a body containing a json object "{ "key": "value" }"
2. Sets the Redis key "key" to contain "value".
3. Waits for the Redis operation to complete and return either success or failure to the downstream user.

This would be the perfect starting point for a personal project that I am about to start. Thanks

Note: I would obviously prefer the server to be based on Boost.Json and Boost.Redis.
