Update docs for specifying how to create a set of tests

[Mikerah]

I think the tests in this repo should conform to the same format. This will make it easier to start new tests for different functionality and onboard new contributors that want to help in adding interop tests.

Any thoughts?

Hello @Mikerah

We decided a format for the tests, but it is not clear in the README and it should be!

Basically, for each type of tests, we create a specific folder for it and then, inside of this folder, we create folders representing the way implementations are being tested. You can check the current tests, as well as the DHT PR in this repo.

Do you have any other suggestions?

@vasco-santos thanks for the reply. Should I keep this issue open until the details of how to format tests are added to the README? Or should I create a separate issue for that?

I updated the name of the issue and the labels for it
