DP Leftovers in the Analytics docs

At the end of https://docs.couchbase.com/server/6.0/analytics/run-query.html there is a paragraph

In addition to submitting queries to the Analytics Service you can also use the REST API for administrative purposes. E.g. you can retrieve version information for the Analytics Service with
$ curl http://localhost:8095/analytics/version
and access the cluster configuration with
$ curl -u Administrator:password http://localhost:8095/analytics/cluster

It needs to be removed as the APIs were only available in the Developer Preview in 5.5 and are not available in 6.0.
