title: Disable PWA plugin in Vue CLI 3
body: <p>I'm having some issues with caching my files using the default service worker that comes with VueCLI 3. I would prefer to just use the default browser caching mechanism, but can't seem to disable the PWA plugin as its not in the <code>vue.config.js</code> file. Passing a blank object to the <code>pwa</code> option doesn't work either as the object is merged and not overwritten. </p>
