Async backing enablement checklist #3226
Description
The purpose of this ticket is to collate together all the needed things to be able to safely enable async backing on kusama and polkadot, in chronological order.
Kusama enablement
- Kusama runtime-api supports async_backing params. Async backing is not enabled, but all the necessary subsystems become live and used in producing parachains blocks at 12s rate(sync_backing).
- Kusama runtime deployed with fix 97df9dd from polkadot-sdk1.7.
- Confirm pre-async backing parachains are not affected by a relay-chain with async backing enabled.
- Confirm parachains that support async backing run correctly on a relay-chain with async backing disable.
- Deploy system parachains with async backing enabled on Westend relay chain with async backing enabled and confirm they work correctly.
- Deploy system parachains with async backing enabled on Rococo relay chain with async backing enabled and confirm they work correctly.
- Enable async backing on kusama with the following steps Propose async backing parameter change on Kusama #2236.

Polkadot enablement
- Confirm validators are running at least a version containing Kusama parachains not producing blocks for a session #3058
- Polkadot runtime-api supports async_backing params. Async backing is not enabled, but all the necessary subsystems become live and used in producing parachains blocks at 12s rate(sync_backing).
- Polkadot runtime deployed with fix 97df9dd from polkadot-sdk1.7.
- Kusama is running with async backing enabled.
- Enable async backing on polkadot with the following steps Propose async backing parameter change on Kusama #2236. Referendas https://polkadot.subsquare.io/referenda/688 & https://collectives.subsquare.io/fellowship/referenda/102
