forms-table: Support for Form Edit Display Control in gauge-commons

[bharatak]

The Forms Edit Display Control looks like this. Create support for it bahmni-gauge-commons like this ObsDisplayControl

This class should accept WebElement as a constructor. It should expose the below methods

List getValues(){} - Returns the list of forms that are configured on the display control.

Future enhancements could be based on the edit part of the display control. It is out of scope for this card.
