use interceptors for argument and response logging

[fbielejec]

Problem

GQL resolvers implement the same pattern of logging the arguments, binding the response in a let ninding, logging the response and returning.
Example

Existing endpoints would be greatly simplified by adding an interceptor / middleware that logs those for every request

Implementation

Known steps towards feature implementation.
What needs further specifying and investigating.

Acceptance Criteria

• argument and response logging middleware
• resolvers cleaned of log calls

Notes

It is possible to replace the webserver with ring or yada if assignee deems it necessary. In such a case it would be nice to keep a GraphQL ide, for example with:
