RPC: http cache header mod

Ryan Tan requested to merge ryan@http-cache-headers@rpc-http-cache-header-mod into master

What

Relative (head-n) queries are always changing which creates friction for integrating Octez RPCs with generic Caches as operators needs extra logic/heuristics to know when to invalidate such a response. To get around this, we introduce relevant HTTP Cache headers into the responses of Octez RPCs. The headers to be implemented are Expires and If-None-Modified. This is an ongoing work with multiple MRs.

Adds the skeleton of Http cache headers module. The 2 inner function parse_block_uri and add_headers will be used by all other middleware of this type.

1/n

Why

Base module for implementing http cache headers middleware.

How

Implements the skeleton mod.
