When the user visits Fleet for the first time, Fleet runs setup to install some required packages and many setup. This currently takes (too) long. When setup was initially built, it contained very few steps but packages grew over time and also the required packages. Along the way also things change. We should evaluate if the way setup is built is still the right way to go today and if things can be optimised / changed. Some ideas:

• Reduce the number of required packages.
  • Example: Is endpoint really required or could be installed on first policy?
• Not directly install assets but only the required ones to ingest data
• Have it done by Kibana in the background: Allow Kibana to setup the stack #89827
• Install assets in parallel (if we don't already do it)
