REST API parameter needs a more intuitive name

REST API as documented at:

http://developer.couchbase.com/documentation/server/4.0/rest-api/rest-node-provisioning.html

// Setup Services
curl -u Administrator:password -v -X POST http://[localhost]:8091/node/controller/setupServices
-d services=[data | index | n1ql]

The parameter value should be changed "n1ql" to "query" as that is more intuitive.
