Clock skew causes missing summary and confuses Calamari

Always provide summary for non-healthy cluster.
This fixes a problem, wherein calamari does not provide
popup drill-downs for warnings or errors, should the summary
Calamari gets health info from /api/v1/cluster/$FSID/health.
If the data here has a summary field, this summary is provided
in a popup window:
/api/v1/cluster/$FSID/health is populated (ultimately) with
status obtained via librados python bindings from the ceph
cluster. In the case where there's clock skew, the summary
field supplied by the ceph cluster is empty.
No summary field, no popup window with more health details.
