cargo new: automatically add to workspace

[theduke]

Problem

When running cargo new in a workspace a warning is printed, but you have to manually add the new crate to the members = [] section.

Proposed Solution

Add a new --workspace / -w flag to cargo new that automatically adds the new crate with the correct path to members.

Print a hint about the flag when cargo new is run in a workspace.

This is admittedly a small quality of life feature, but I do it often enough that it becomes annoying.

Thanks for the report. This is a known issue, closing as a duplicate of #8365.

@ehuss these are two different requests.

The other issue is about creating an empty workspace.

This issue is about automatically modifying the members declaration in a workspace when running 'new' inside a workspace.

Sorry, I should have linked to #6378.
