To avoid empty space above layout option group

move layout properties to layout options group in widget

This reverts commit a5a1d44.

* Expose Dataplotly on QGIS Server for a GetPrint request

* Fix tests about lint

Float now requires explicit cast to int

* Add options to change title, xticks and yticks font sizes.

Insert options in graph parameters to change settings for all three parameters.

Could be refined to also change x_label and y_label font sizes (if such parameters
exist)

* Add options for x/y labels and put all box in a collapsible group

* Update UI parameters (title, collapsed state, default values)

* Update default font size (ui and python).

* Use QgsFontButton instead of size input only.

Still needs some work to keep in mind the parameters between two sessions.

* Separate parameters into family, size and color

* Test if font related settings are correctly stored and restored.

* Fix pylint issues
