Implement
pallet-asset-rewards (paritytech#3926)
Closes paritytech#3149 ## Description This PR introduces `pallet-asset-rewards`, which allows accounts to be rewarded for freezing `fungible` tokens. The motivation for creating this pallet is to allow incentivising LPs. See the pallet docs for more info about the pallet. ## Runtime changes The pallet has been added to - `asset-hub-rococo` - `asset-hub-westend` The `NativeAndAssets` `fungibles` Union did not contain `PoolAssets`, so it has been renamed `NativeAndNonPoolAssets` A new `fungibles` Union `NativeAndAllAssets` was created to encompass all assets and the native token. ## TODO - [x] Emulation tests - [x] Fill in Freeze logic (blocked paritytech#3342) and re-run benchmarks --------- Co-authored-by: command-bot <> Co-authored-by: Oliver Tale-Yazdi <[email protected]> Co-authored-by: muharem <[email protected]> Co-authored-by: Guillaume Thiolliere <[email protected]>
