This PR implements a method of correlating files from the diff to test files based on how they have changed together over the history of the project. The raw information (only file names) is sent to the backend where we use an algorithm determine the probability of correlation. We then use this information to order the tests such that the tests which are correlated to files in the diff are run first.
Doing this requires a target branch, so it'll only happen in the PR scenario, and only if the target branch is provided to selective. We fetch 1000 commits on the target branch by default, but this will be configurable via the selective dashboard in the future.
