Throw FeatureNotAvailableException when query preserve expiry is not supported

If the user sets queryOptions().preserveExpiry(true) with a pre-7.1 cluster, they get a CouchbaseException with message "Unknown query error" and context that includes

[{"code":1065,"message":"Unrecognized parameter in request: preserve_expiry"}]

We can translate this into a more informative FeatureNotAvailable exception (like we do when the user tries to query a scope on a pre-7.0 cluster.

Suggested release note: NONE, since `queryOptions().preserveExpiry()` method was added in the same version.
