Hmm this breaks our warpsync zombienet test, I will generate new snapshots. |

Part of #3168 On top of #3568 ### Changes Overview - Introduces a new collator variant in `cumulus/client/consensus/aura/src/collators/slot_based/mod.rs` - Two tasks are part of that module, one for block building and one for collation building and submission. - Introduces a new variant of `cumulus-test-runtime` which has 2s slot duration, used for zombienet testing - Zombienet tests for the new collator **Note:** This collator is considered experimental and should only be used for testing and exploration for now. ### Comparison with `lookahead` collator - The new variant is slot based, meaning it waits for the next slot of the parachain, then starts authoring - The search for potential parents remains mostly unchanged from lookahead - As anchor, we use the current best relay parent - In general, the new collator tends to be anchored to one relay parent earlier. `lookahead` generally waits for a new relay block to arrive before it attempts to build a block. This means the actual timing of parachain blocks depends on when the relay block has been authored and imported. With the slot-triggered approach we are authoring directly on the slot boundary, were a new relay chain block has probably not yet arrived. ### Limitations - Overall, the current implementation focuses on the "happy path" - We assume that we want to collate close to the tip of the relay chain. It would be useful however to have some kind of configurable drift, so that we could lag behind a bit. #3965 - The collation task is pretty dumb currently. It checks if we have cores scheduled and if yes, submits all the messages we have received from the block builder until we have something submitted for every core. Ideally we should do some extra checks, i.e. we do not need to submit if the built block is already too old (build on a out of range relay parent) or was authored with a relay parent that is not an ancestor of the relay block we are submitting at. #3966 - There is no throttling, we assume that we can submit _velocity_ blocks every relay chain block. There should be communication between the collator task and block-builder task. - The parent search and ConsensusHook are not yet properly adjusted. The parent search makes assumptions about the pending candidate which no longer hold. #3967 - Custom triggers for block building not implemented. --------- Co-authored-by: Davide Galassi <[email protected]> Co-authored-by: Andrei Sandu <[email protected]> Co-authored-by: Bastian Köcher <[email protected]> Co-authored-by: Javier Viola <[email protected]> Co-authored-by: command-bot <>

Cumulus test-parachain node and test runtime were still using relay chain consensus and 12s blocktimes. With async backing around the corner on the major chains we should switch our tests too.
Also needed to nicely test the changes coming to collators in #3168.
Changes Overview
validate_block, I introduced a helper function for that
