Add DM support to Teaser component (adobe#2350)

- provide servlet to include asset tab from image component into the the teaser dialog. In this case the cqDesign request attribute needs to be reset to the imageDelegate component
- move the DM settings from the metadata tab to the asset tap in the image dialog, so it is still only required to include the asset tab within the teaser dialog

relates to adobe#1473
