Create a bootstrap that allows creation of contract-specific command line tools

[frol]

I believe that it will greatly improve the DevX of contracts if developers can have a way to easily bootstrap a CLI tool for a contract (to have a dedicated tool instead of using near-shell with manual JSON crafting).

Thus, instead of

near call my_validator deposit '{}' --accountId user1 --amount 100
near call my_validator stake '{"amount": "100000000000000000000000000"}' --accountId user1

a contract user will have a specific interface, thus minimizing the scope (no need to understand and remember the JSON format) and reducing the room for an error:

npx near-staking-pool my_validator deposit-and-stake 100N

Another example where we already want to have a CLI for a contract: near/bounties#10

This issue is somewhat related and more general purpose for calling any contract: near/near-cli#367

[frol]

@willemneal that API might still be too low-level. Yet, I agree that we can explore the space of generic solutions as well, but in order to make is user-friendly we need to solve the contract metadata problem (a.k.a. contract interfaces)

@frol do you mean instantiating dependency objects automatically a-la near repl or something else?

[frol]

@vgrichina Yes, near repl-like instantiation with CLI framework in place, so developers will only need to add new CLI subcommands calling await contract.welcome({ account_id: "frol" })
