feat: manual sort for query parameters

[krummbar]

Description

Fixes #2053

Adds sorting capabilities to the request query parameters. It uses react-dnd internally. Sorting happens already while hovering other items, but changes are only permanent if the request object is saved.

I moved the rendering of the individual table rows into a dedicated file for better separation. Let me know if I should revert this and move everything back into the index.js.

I'm not 100% happy with the solution as it requires copy & paste if this kind of sorting should apply to other components. I see a valid use-case adding this to request headers, vars and asserts as well. It would be possible to move some of the logic into a common utils location, but this increases complexity about the internal workings due to abstraction. If this is the way forward I can refactor here a bit.
