'life0: 'async_trait,
Wait for a given relay chain block
The hash of the block to wait for is passed. We wait for the block to arrive or return after a timeout.
Implementation:
- Register a listener to all new blocks.
- Check if the block is already in chain. If yes, succeed early.
- Wait for the block to be imported via subscription.
- If timeout is reached, we return an error.
