Changes:

• Updated the view-profiles, get-profiles, edit-profile, and upload-profile actions to send requests to the connected Fleet instances and process results simultaneously.

I tested these changes while connected to a Fleet instance running on the same network as my device, here is what I saw:

• Loading the profiles page with four profiles assigned to 22 teams:
  • Current version: 3232ms
  • This PR: 699ms
• Uploading a configuration profile with custom label targets to 22 teams:
  • Current version: 5660ms
  • This PR: 865ms
• Editing a configuration profile that is assigned to 22 teams labels:
  • Current version: 6622ms
  • This PR: 1300ms
