chore: Seperate test processor logic into its own service

[StefanNemeth]

Motivation

Right now the test processor is part of the application server code. However, with increasing complexity of the processor that could lead to some maintainability issues in the future.

Description

This PR seperates the downloading of test artifacts, extraction of zip files and parsing of test files into its own microservice called test-processor. I'm making use of our existing NATS service for communication. Additionally, the test processor provides the actual results with a REST API as the data is too large for sending it via nats.

Testing Instructions

Displaying test results: Try to generate some test results (see test instructions of #341) on your branch/PR. You'll need to run the test processor as well (run ./gradlew :test-processor:bootRunDev within server directory). Also make sure that your .env file is moved to the server directory.

Checklist

General

• PR description explains the purpose and changes. (f.e. following the 'Conventional Commits')
