Slots * some registrar tests * Apply suggestions from code review Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com> * Update runtime/common/src/slots.rs Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com> * Slots uses Registrar for CurrentChains * swap works test * on swap impl * traitify parachain cleanup * explicit lifecycle tracking for paras * initial implementation of lifecycles and upgrades * clean up a bit * Update runtime/common/src/slots.rs Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com> * fix doc comment * more rigid lifecycle checks * include paras which are transitioning, and lifecycle query * format guide * update api * update guide * explicit outgoing state, fix genesis * handle outgoing with transitioning paras * Revert "explicit lifecycle tracking for paras" This reverts commit 4177af7ba473bbd9c26bccd861793f25265b6657. * remove lifecycle tracking from registrar * do not include transitioning paras in identifier * Update paras_registrar.rs * final patches to registrar * Fix test * use noop in test * clean up pending swap on deregistration * finish registrar tests * Update

reverts commit b2e9011ec8937d6c73e99292416c9692aeb30f73. * Traitify Auction interface. * Mockups and initial code for Crowdloan testing * One test... * collapse onboarding state * fix some crowdloan tests * one more * start benchmarks for auctions * benchmark bid * fix more crowdloan tests * onboard and begin retirement no longer exist * Revert "onboard and begin retirement no longer exist" This reverts commit 2e100fd94e3540bff5f172328b5d917896f1c6fc. * Simplify crowdloan and make it work. * Fixes * fix some * finish merge fixes * fix refund bug in auctions * Add traits to Registrar for tests and benchmarks * fix more auction benchmarks * Fix TestAuctioneer * finish crowdloan benchmarks * start setting up full integration tests * expand integration tests * finish basic integration test *
