v3.0.0-rc2

This release includes v1 of the Interchain Accounts application module. 🍾

This is the first major feature addition since the v1.0.0 release of ibc-go. 👏

Kudos to everyone that has contributed to this feature on protocol design, implementation, testing and auditing. 🙏

Shout-out to the team at Chainapsis for the brilliant work that kick-started everything. 🌟

And last but not least, we want to thank @seantking for leading the efforts to bring all this to fruition.🥇

At a high level, when comparing to v3.0.0-rc1 this release:

• fixes the migration documentation for adding store upgrades for the ICS27 module .

• adds `counterpartyChannelID` to argument list of the `OnChanOpenAck` callback in the IBCModule interface.

• fixes the rejection of redundant packet messages within the same block. This fix entailed replacing the field of type `channelkeeper.Keeper` in the `AnteDecorator` structure with a field of type `*keeper.Keeper`.

Please see the CHANGELOG for the full set of changes included in this release.

Please read the migration doc , which provides information on updating from v2 to v3.
