Etcd api-gateway watch error

[anthonydevelops]

Currently, watching using Node Webhooks has an issue when using Etcd's api-gateway, specifically with watching. Using the watch api request used to work but stopped randomly after working with the node error:

MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 connection listeners added. Use emitter.setMaxListeners() to increase limit

Change the following code in /client/server.js to that of how Etcd's doc uses watching to see that nothing is returned:
This: webHooks.add('etcd', http://${etcd}/v3beta/kv/range)
To this: webHooks.add('etcd', http://${etcd}/v3beta/watch)
