Subject: [PATCH] feat(AgmMap): add gestureHandling option

The gestureHandling attribute in MapOptions controls how
gestures on the map are handled. The attribute takes one
of four string values (cooperative, greedy, none and auto).

Changes are not breaking, gestureHandling is an optional
attribute and the google maps api defaults this attribute to
'auto'.

Closes #919
