[RFC] `aptos move new-package` feature

[mkurnikov]

🚀 Feature Request

@movekevin on the call proposed to add a command to Aptos CLI, which would allow users to create their packages from templates.

This is my PR https://github.com/aptos-labs/aptos-core/pull/5727 for the feature. I've implemented what was my take on the design. In the PR review, there was a suggestion https://github.com/aptos-labs/aptos-core/pull/5727#issuecomment-1345444814 to make a proper discussion out of it.

My take is:

aptos move new-package [-t TEMPLATE_NAME] PACKAGE_NAME

default of TEMPLATE_NAME would be empty, which will correspond to the current aptos move init.

There's also a -t coin for the coin contract, and -t dapp for the frontend app.
