* /api/latest/fleet/hosts now returns `critical_vulnerabilities_count`
for premium users. This data is held in the new `host_issues` table. The
failing policies total is updated in real-time, while the critical
vulnerabilities total is updated every hour after vulnerabilities job.
* /api/latest/fleet/hosts can be sorted by total_issues_count by
specifying `order_key=issues` query parameter.
