Generalize CLI command for query connection/channel end

[soareschen]

Part of #392.

Summary

This task focuses on generalizing the CLI code for querying the connection end and channel end. The generalized components can be placed in the hermes-cli-components crate.

You can check related PRs such as #391 on how this can be done.

Things to note

• The original CLI checks for whether the state is uninitialized, and return error if so. This is not needed for the generalized CLI, as the ConnectionEnd type is generic. This would already been handled by the Cosmos-specific implementation of CanQueryConnectionEnd.
• We don't need to use AnyCounterparty in the query, as the type of the connection end depends on the target chain.
