Subscriber User can create URL at AML Campaign level ( no longer create different Destination URLs for each ad)

DEMO: user will no longer be able to create different Destination URLs for each ad. Only at the BA+Location level.

To support the value track tags for Telmetrics (and other call providers), we will need to use keyword URLs.

If necessary for tracking keywords and ads through Google Analytics, AML backend will create Keyword URLs instead of Ad URLs with utm_ parameters.

need UI example for moving the custom URL up to BA+Loc. This will be handled the same way we handle Display URL today - when the user enters a display URL from the Edit Ads UI, that display URL will be automatically applied to the other 3 ads.
