🚀 Highlights

This is a major ICS release that brings a series of improvements to both provider and consumer chains.

• Remove the VSCMaturedPackets from the consumer module (as per ADR 018).
• Add a priority list to the power shaping parameters.
• Remove the governance proposal whitelisting from consumer chains.
• Enable the chain ID of a consumer chain to be updated after creation, but before launch.
• Enable querying the provider module for the genesis time for a consumer chain.
• Enable consumer chains to have customizable slashing and jailing (as per ADR 020).
• Simplify the changeover from standalone to consumer chains by reusing the existing IBC connection to the provider.

In addition to the above improvements, this release also adds interchain tests to ICS. This is an effort to simplify the testing framework and increase the confidence of ICS releases.
