Minimal implementation of Sovereign chain context to support packet relaying

[soareschen]

Summary

The chain context dependencies that are required for the default packet relayer to work is specified in the constraint closure here:

hermes-sdk/crates/relayer/relayer-components/src/components/default/closures/relay/packet_relayer.rs

Lines 46 to 85 in ed9161c

To support packet relaying, the sovereign chain context would need to at minimum implement the traits specified in the constraint closure. This issue would track the major implementation progress.
