DashboardSections should support any header component

[eforest]

Describe your motivation

Currently DashboardSections can have (as far as I could determine) only a simple title (via sectionTitle property).
I'd like to provice an "add" button for my sections, so that a user can add additional widgets to the given section.

Therefor DashboardSections should support any header component, similar to DashboardWidget.

Describe the solution you'd like

DashboardSections should support any header component, similar to DashboardWidget.

Describe alternatives you've considered

My current workaround is to have Dashboards in Dashboards (which works, but is complicated to handle).
I.e. instead of a DashboardSection I use a DashboardWidget with add button in the header and another Dashboard as content.

That's a good idea, makes perfect sense. Let's see if we can add that in a future minor version.
