GoXDCR: Response of REST call to create remote-cluster reference/replication has changed in goxdcr(default in Sherlock)

Replication creation
---------------------------

Until Sherlock(not including), creating replication through REST would return a response like

{ "id": "9eee38236f3bf28406920213d93981a3/beer-sample/remote_beer", "database": "http://10.4.2.4:8092/_replicator" }

Goxdcr in Sherlock will however only return

{ "id": "replicationSpec_9eee38236f3bf28406920213d93981a3/beer-sample/remote_beer", }

remote cluster reference creation
----------------------------------------------

until Sherlock, response was -

{"name":"remote1", "uri":"/pools/default/remoteClusters/remote1", "validateURI":"/pools/default/remoteClusters/remote1?just_validate=1", "hostname":"10.4.2.6:8091", "username":"Administrator", "uuid":"9eee38236f3bf28406920213d93981a3", "deleted":false}

Goxdcr response to creating a cluster reference in goxdcr -

{"id":"remoteCluster_b8df7219248b2322837ed5e9a83e260f", "uuid":"b8df7219248b2322837ed5e9a83e260f", "name":"remote1", "hostName":"10.3.4.188:8091", "userName":"Administrator", "password":"password", "demandEncryption":false, "certificate":null}

Xiaomei, pls add a line for the deleted/new fields so it can be used for documentation.

CCing Anil to check if this might break the Elastic Cluster connector.
