Service-discovery deletes the pool members for each sd modification

[jrooty]

This request is related to the service-discovery behavior.

On service-discovery configuration, changing uri or servicePort, the current behavior is to delete all pool members (retrieved previously) and wait until the next discovery (based on updateInterval) to get new pool members.

Based on that, changing either uri or servicePort will disturb the traffic.

What we see also, based on new feature #759, if we change the content of adminState (could be enabe, disable or offline), we observe the same behavior : all pool members are removed until the next pooling. That behavior makes useless #759 as we lost all pool members...

I understand that if we modify uri or servicePort, we should expect new members as we will target new service-discovery service. However, if we change adminState, priorityGroup or other, it shouldn't impact the service (why remove pool members?)

We need a behavior change at least for adminState, priorityGroup or other : do not delete the current pool members. It does make no sence to delete pool members here.

If technically, it is possible to apply this change for uri or servicePort, it can be helpfull as well.

Here an extract of the AS3 declaration :

members": [
                    {
                        "servicePort": 30988,
                        "addressDiscovery": "consul",
                        "autoPopulate": true,
                        "uri": https://first.sd.com/,
                        "updateInterval": 30,
                        "rejectUnauthorized": false,
                        "shareNodes": true,
                        "adminState": "disable",
                        "priorityGroup": 10
                    },
                    {
                        "servicePort": 30988,
                        "addressDiscovery": "consul",
                        "autoPopulate": true,
                        "uri": https://second.sd.com/,
                        "updateInterval": 30,
                        "rejectUnauthorized": false,
                        "shareNodes": true,
                        "adminState": "enable",
                        "priorityGroup": 5
                    }
                ]

Thank you.
