Add Java DSL for GraphQL (#3934)

Browse Source 
* Add Java DSL for GraphQL

* GraphQl.outboundChannelAdapter() -> outboundGateway()

* * Add `private` ctor to `GraphQl`

* * Just `GraphQl.gateway()` - there is not going to be any other components
to handle GraphQL operations.
Also, the `outbound` in the name might confuse, where we, essentially, query a GraphQL data

* Fix typo in the doc
