Feature: Allow to collapse composite health components

[cdprete]

Hello.

Enhancement
It would be great if composite health components like the following

would be collapsible, in the sense that a button is present to open/close the accordion and, when closed, to just show the overall health of the composite indicator.

Ideally health groups and composite health indicators should be handled, trasparently, in the same way.
From a UI point of view, in terms of monitoring, there is really no benefit in knowing that a single indicator X is part of a group or a composite indicator.
