New slots/auctions architecture (#2294)

* TODOs * Add auctions.rs, comment on changes needed. * Remove cruft from slots * Remove more from auctions.rs * More logic drafting in slots. * More logic in slots.rs * patch some errors * more fixes * last nit * Cleanups in slots.rs * Cleanups in slots.rs * patches * make build * crowdloan to new api * auction compile * Use ParaId instead of FundIndex in Crowdloan (#2303) * use paraid instead of fundindex * Update crowdloan.rs * check caller is manager * Auction tests and fix build warnings. * Configurable origin for initiating auctions * Remove on_finalize * #2303 (manual merge) * Tests for 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 roadmap/implementers-guide/src/runtime/paras.md * Update roadmap/implementers-guide/src/runtime/paras.md * Update roadmap/implementers-guide/src/runtime/paras.md * Apply suggestions from code review * Use matches macro * Correct terms * Apply suggestions from code review * Remove direct need for Slots and Registrar from Crowdloan * Rejig things slightly * actions queue * Revert "actions queue" This 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 * add more integration tests * begin slots benchmarks * start paras registrar benchmarks * fix merge * fix tests * clean up paras registrar * remove println * remove outdated cleanup config * update
