Refactor the wasp-cli

The wasp-cli has grown over time and in my opinion, needs some focused improvements:

* Contains unused legacy functions (they don't function anymore, don't do anything, or panic)
* Misses more important functionality (e.g., parsing contract call args)
* Even with all the available commands, it's difficult to get a clear picture of the Chain.
* Lacks proper command documentation in help listings
* No structured output options (JSON) for programmatic consumption
* Asset parsing and key management needs improvement
* Our cluster tests rely on RegEx parsing of CLI output, due to the missing JSON output
* Some commands require a connection to an ISC node, even when it's not needed (Deposits and general on ledger requests for example)

I propose we:

* Replace Viper with a lighter alternative to reduce dependencies and size
* Make the cli only rely on the WebAPI where possible, and keep the wasp dependency to the most minimum, if possible down to 0.
* This will at least for the chain deployment require us to provide a new API Route to initialize an empty chain (which is simple)
* Introduce a formatting library like `glazed` to provide different output formats
* Remove unused commands to streamline the codebase
* Improve the code base overall, especially refactoring code duplication
* Introduce new commands to give a better oversight of the chain, blocks, requests and execution status

This would improve developer experience, make testing more reliable, and provide better integration with other tools.
