Implement minimal CLI for Starknet relayer

[soareschen]

Currently we have a minimal CLI for Starknet available with a simple bootstrap subcommand. We have a few more generic CLI components in Hermes SDK that can be imported to be used the Starknet CLI.

For commands that do not yet have generic implementation, we should implement the context-generic versions of the CLI components on Hermes SDK before importing them here.

Following are a rough list of CLI commands that should be made available:

• Query chain status Add query chain-status CLI #159
• Query client state Add query client state CLI #148
• Query consensus state Add query consensus-state CLI #151
• Perform update client Add client update CLI #158
• Query wallet balance
