`near delete` with positional arguments is dangerous

[evgenykuzyakov]

Is your feature request related to a problem? Please describe.

Current API supports the following:

 near delete <accountId> <beneficiaryId>

It's really easy to mess up the arguments and delete the beneficiaryId account instead of accountId.

Describe the solution you'd like

There are 2 possible solutions:

• Confirm each request. This should be on by default and overridden with -y. This way the shell will first display the action you want to do and then ask you to confirm it. Will prevent accidental mistakes.
• Make account ID and beneficiary ID named required arguments instead of positional.
