Peer management multiple PUT request doesn't disconnect properly.

[AdamMagaluk]

Notice there seems to be a weird case if you perform multiple PUT request on a peer with a url to the original cloud server it creates multiple connections after first request.

Example: Hub1 -> Cloud

curl -X PUT --data url='http://cloud' http://cloud/peer-management/<connection_id_1>

At this point hub1 will disconnect from cloud and reconnect back to cloud.

To force a second disconnect:

curl -X PUT --data url='http://cloud' http://cloud/peer-management/<connection_id_2>

After this request the hub goes into a loop trying to connect to the cloud but receives a 409 conflict because it's already peered.

When using the method PUT on a peer should we be creating a new peer connection? Or just updating the existing one's url?
