Facilitate Switch to Dependency Manager on Existing Projects

[chasefleming]

In order to more easily migrate people with existing projects to use Dependency Manager, we should facilitate the switch easily. This means:

• And existing project adds a dependency
• If it detects that dependency in contracts it asks the user if they'd like to remove it from contracts since it will be in dependencies
• It pulls the aliases (may request permission)
• It gives a summary of files you can now delete from your project

There are still some incompatibilities with the dependency manager in VS Code.
I have to configure the same contract twice in contracts and dependencies to ensure that flow.json works properly.

Of course, the advantage is that I don't have to submit these contracts to the repo anymore, because they are under imports folder.

For your refer:

I'm not sure this is related to this ticket, but it looks like it was resolved on the linked issue.

Yeah, I found that it has been fixed in flow-cli v1.18.0 .
