feat: support file upload in router

[pedraumcosta]

Motivation and Context

This PR makes possible to support a file upload according to spec:

https://github.com/jaydenseric/graphql-multipart-request-spec

This PR depends on this PR from graphql-go-tools:

wundergraph/graphql-go-tools#758

This PR parse multiform part http requests with files, saves in the file system and passed the file information along the graphql tools library to be forwarded to a subgraph that supports files uploads. In order to make tests possible, I added file uploads operations to the demo employee subgraph and some enhanced methods to test infrastructure.

TODO

• Tests or benchmark included
• Documentation is changed or added on https://app.gitbook.com/
• PR title must follow conventional-commit-standard

Any news about when this will get merged or if it will be? We are also using multipart request on several projects and waiting for this fix. Thank you!

Hi @alexandra-c

There is no time box for pull requests such as this. Please understand that our capacity is limited, and while we strive to review PRs as soon as possible, our priorities are dictated by our existing customers.

Thank you for your patience.
