Support for Couchbase Analytics

Couchbase server 5.5 supports a pre-release version of Couchbase Analytics. The query syntax is ANSI SQL as is N1QL, so providing linq support should be possible via configuration since the endpoint service and the response are the two things that differ since the emitted N1QL should work in either case.

Note that there may be additional work required to understand the full scope of the integration. Additional tickets may be opened.

Start by reviewing how configuration selects the endpoint service and how responses are handled, then compare those paths with the emitted N1QL and ANSI SQL compatibility described in the issue. Done means establishing the full integration scope and confirming whether LINQ queries work against Couchbase Analytics; additional tickets may be needed.
