Show credits/attribution text in printed page

[ale-cristofori]

Description

At the moment the textual attribution, credit or copyright statement are not visible on the printed map. The default attribution can be shown in OSM and can be customized for the WMTS layers. The text in question appears on the screen and on the map print preview but not on the resulting printed map.

Acceptance criteria

• As a MapStore USER with a role that allows me to edit a BG layer I edit the attribution text of a WTMS layer, I then click on the print button and open the print dialog window, when clicking on print I should be able to see the edited text appearing on the printed page.
• As a MapStore USER I Open a map and I visualize as BG layer OSM, the usual OSM attribution text appears on the bottom of the map, when I click on print the text appears on the map print preview and it will also appear on the printed Map.

Other useful information

Attribution can be found not only on BG layers but also on overlays, in that case the text is cumulative (one attributions for each text requiring it)

The solutions found needs to be as dynamic as possible, a solution that could fit all the text in a text box to be shown on the map, without cutting it. Another solution, if the text is too long is to provide it separated from the map, on a separate page.
