Enable ETags

[ptrwtts]

ETags are a way to check if a response is the same as what the client already has in cache, and if so, not re-send the same data. It doesn't save us compute / db load, but it will make the response feel faster, especially for large resources like the attributes.

I found a plugin for this, but I'm not sure we need it. The docs suggest that you just need to pass a single field, which can be a checksum of the response object.

Ideally, it can be enabled universally at the server level, to keep the code for each route clean, but it's not critical.
