Implement the first version of a GraphQL query cost calculator as a middleware.

== Task description ==

Since GraphQL exposes a graph, queries could get really complex and can add a lot of load to the storage systems.
Eg: A query like [https://forge.softwareheritage.org/P1305 this] will execute at least 4 different storage queries in a single request.

Though it is possible to restrict queries by size/length, a basic query cost calculator is a necessity.
The very first version can be implemented as a GraphQL middleware.
This will involve finding the relative complexity of a query in the backend and some basic
arithmetic to calculate the total query cost.
The resulting number can be used to accept or reject a query.
The same number can later be used for user level throttling and rate limiting as well.

== Desirable skills ==

* Python
* Basic knowledge of a middleware.
* SQL
