Add end-to-end tests to our CI

Fix #4234

This PR adds end-to-end testing to our CI.

Specifically, it:

1. Adds and sets up a real server to our Drone pipeline
2. Adds a end to end testing utilities class that makes it easier to test with the server set up in the CI
3. Adds a test checking the correct set-up of an account
4. Adds a test checking file transfer (down-syncing an existing file, creating and uploading a new file, and deleting said created file)

how would you run the tests locally on a dev setup ?

how would you run the tests locally on a dev setup ?

You could either:

• Set up drone locally
• Pull the docker container from our docker-ci images and point endtoendtestutils.cpp to the address which the local docker sets up
