tests: Add new, data-driven OTA tests
Rather than writing one test class with associated method for each OTA algorithm / test, let's do this in a data-driven way, where new test cases just have to provide test data, while the code iterates over it. Change-Id: I8789a21fa5a4793bdabd468adc9fee3b6e633c25
