Node Templates - return with $return or return object

[mhoeger]

context.bindings.namedOutput is currently the default, but it is likely a better async JS functions pattern to use return values, either by directly returning and using $return, or by returning the object. Here is some more context: Azure/Azure-Functions#431

From issue:

As a newbie, knowing to change host.json to use $return instead of res falls into category of somewhat arcane rule (albeit easy enough to understand once pointed to that direction) - prior to change, seemingly basic stuff wouldn't function as expected (promises or otherwise), even after consulting copious amount of literature on js/async/promises/etc. ... today I'd throw a +1 vote for having the defaults sticking to what I perceive to be the relatively better known concept of $return.
