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 - Followed the [migration guide](https://wiki.polkadot.network/docs/maintain-guides-async-backing) for async backing for the cumulus-test-runtime - Adjusted the cumulus-test-service to use the correct import-queue, lookahead collator etc. - The block validation function now uses the Aura Ext Executor so that the seal of the block is validated - Previous point requires that we seal block before calling into `validate_block`, I introduced a helper function for that - Test client adjusted to provide a slot to the relay chain proof and the aura pre-digest
Aura Module
Overview
The Aura module extends Aura consensus by managing offline reporting.
Interface
Public Functions
slot_duration- Determine the Aura slot-duration based on the Timestamp module configuration.
Related Modules
- Timestamp: The Timestamp module is used in Aura to track
consensus rounds (via
slots).
