v2.2.0-rc2

Highlights

• Fixes a bug when querying the unbonding period for ICS consumer chains. This bug made it problematic for the relayer to create clients tracking consumer chains. (#1044)
• Separates recv_packet event handling from write_acknowledgement event handling, making async ack flows possible, such as for multi-hop atomic transfers strangelove-ventures/packet-forward-middleware#36 (#1038)
• Fixes a bug where timeouts are batched on an ordered channel, making it impossible to close an ordered channel when multiple sequences are timed out simultaneously. (#1045)
• Improves chain registry fetches to avoid rate limits (#1013)
