Attach `.nodeChildProcess` to the execa promise

[sindresorhus]

Node.js does this now for childProcess. when you promisify it.

https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback

The name is to be decided.

One day, I hope we can get rid of execa() being both a childProcess and promise and just have the .child property on the promise. But that's a huge breaking change. For now, the best we can do is to add it, and recommend new users to use it instead of the old way. We could even un-document the old way.

@ehmicky Thoughts?

Yes this sounds good :+1:

Any thoughts on the name?

• .child
• .process
• .subprocess
• .childProcess

[ehmicky]

.child since this is the name used by Node.js util.promisify(childProcess.exec)?

I plan to, just have other priorities at work. If someone else gets to it before me that’s fine, my guess is I will be able to do it late next week at the earliest.

Per this comment, we are going to name the property subprocess instead.
