pgAdmin 4 commit: Clean up the unwanted extended versions of Backform S

Clean up the unwanted extended versions of Backform Switch controls.
The Bootstrap Switch Control was extended only for alignment in most
places. IIntroduce a configurable option to set the necessary class
on the main div and also remove the extra extended controls.
