Restructure integration tests according to the integration level #632
Description
Currently, there are the following test types:
- pure unit tests (run locally, no API calls or mocked)
- API integration tests (they run locally, but they do API calls)
- Actor on platform integration tests (they build and start an Actor that runs on the platform)
- Actor on platform + Crawler integration tests (they build and start an Actor that contains a Crawler which runs on the platform)
Restructure folder structure to make it clear where new tests belong, maybe update the makefile
