title: gcloud configuration project filter
body: <p>When listing projects, we can filter on name using: <code>gcloud projects list --filter='name:xxxx*'</code></p>
  <p>How to store this filter in gcloud configuration so everytime we run gcloud projects list we get filtered projects ?</p>
  <p>Note: I don't want a command alias, I need a &quot;per gcloud configuration&quot; filter.</p>
  <p>Thanks</p>
