[Fleet] Unhealthy fleet server in multiple space

[nchaulet]

Description

As part of making Fleet space aware, it is possible there is no healthy Fleet server running in that space, we should define what we should do in that case as it's blocking agent enrollment

To make sure I understand what is happening:

In this case there is actually a Fleet server, and agents could enroll with it, but the agent running Fleet server is not visible in this space?

Yes that's correct, currently the check happen client side we retrieve all the fleet server agents and check if one is healthy.

With spaces we probably want to change that to have that information retrieved server side, and probably check if there one healthy Fleet server accross all spaces.

I think with the changes in #181357, all the checks for the enrollment flyout are happening server-side now, so it should be possible to bypass spaces during the check for fleet server agents.

That's great so it probably just fixing how we retrieve the agents there to check thought all namespaces
