Backward sync support for SyncManager. (#3131) * Unbundle SyncQueue from sync_manager.nim. Unbundle Peer scores constants to peer_scores.nim. Add Forward/Backward enum. * Further improvements and tests. * Adopt getRewindPoint() and fix MissingParent handler. * Remove unused procedures. Refactor `result` usage. Fix resetWait(). * Add all the tests and fix the issue with rewind point. * Fix get() issue. * Fix flaky tests. * test fixes Co-authored-by: Jacek Sieka <jacek@status.im>
