Started writing up wrappers and unit tests for group config types
Refactored some duplicate batch & prepared request code to be more generic and reusable
Renamed a number of legacy closed group functions to have the term 'legacy' in them for ease of coding
Cleaned up the Dependencies so that tests can run synchronously without having to custom set queues as much
Sorted out the crypto and network dependencies to avoid needing weird dependency inheritance
Fixed the flaky tests so they are no longer flaky
Fixed some unexpected JobRunner behaviours
Updated the CI config to use a local build directory for derivedData (now works with build tweaks)
