N1QL / Query system data into cbcollect_info

I noticed that the N1QL devs often ask for the system data when debugging an issue, this should be added into cbcollect_info

(replacing path for curl, host and port for query services)

/opt/couchbase/bin/curl -v http://localhost:8093/query/service -d "statement=SELECT * FROM system:datastores"

/opt/couchbase/bin/curl -v http://localhost:8093/query/service -d "statement=SELECT * FROM system:namespaces"

/opt/couchbase/bin/curl -v http://localhost:8093/query/service -d "statement=SELECT * FROM system:keyspaces"
