[FR] Hunting packages: Add an endpoint list report from search, based on filters (e.g., threat name)

[sebastiendamaye]

Add a "hunting package" logic.
Add the possibility to get a list of matching endpoints from a search. For example, you have a couple of analytics to match "ShaiHulud" and want to get the list of endpoints that match these analytics. From the search results, add a link to export the list of matching endpoints.
