title: Is there a way to specify angular version with the ng new command
body: <p>I am creating a new Angular project and would like all the Angular dependencies to be from the stable 7th version. However, it seems that while running the <code>ng new app</code> command the Angular always fetches the latest version. My package.json shows all the angular packages like core, animations etc from <code>~8.0.0</code>.</p>
  
  <p>I know that I can modify the package.json and set these dependencies to be fetched as per the semantic 7.x.x, but I would rather want it to be done automatically so that I do not run a chance of mis-matching any peer dependencies.</p>
  
  <p>So, Is there a way that we can tell the CLI to fetch a particular angular version and all the dependencies according to that angular version.</p>
  
  <p>EDIT: I have already tried insatlling @angular/cli@7.x.x. Even after doing this if I run ng new app, my depencies are fetched as per the 8th version</p>
