Allow building with less noise

[arielshaqed]

What

Building e.g. a client package outputs these lines to standard error:

npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN @binaris/[email protected] No license field.

This causes pain e.g. when using Rush.

Give some way to prevent these 2 outputs.

Suggestions:

1. Copy license from package.json of generating package to generated package.json. This doesn't have to be (probably shouldn't be) the license field, it could be instead generated-license. That fixes the "warning" -- which is really always a bug. (Maybe also allow setting private there?)
2. Add an option --npm-install-args so I can pass --npm-install-args=--no-package-lock and get rid of the "notice".
