Identify Stargate nodes

[jdonenine]

Add the ability to identify stargate nodes and distinguish them in the UI.

• Updates the cluster/{name} endpoint response to include a new type property, will either be CASSANDRA or STARGATE

{
   "name":"stargate",
   "jmx_username":"",
   "jmx_password_is_set":false,
   "seed_hosts":[
      "127.0.0.2",
      "127.0.0.1"
   ],
   "repair_runs":[
      
   ],
   "repair_schedules":[
      
   ],
   "nodes_status":{
      "endpointStates":[
         {
            "sourceNode":"127.0.0.1",
            "endpoints":{
               "datacenter1":{
                  "rack1":[
                     {
                        "endpoint":"127.0.0.2",
                        "hostId":"bed76ae4-10c4-4f3b-af4b-e245011dbcc3",
                        "dc":"datacenter1",
                        "rack":"rack1",
                        "status":"Not available",

                        "tokens":"",
                        "load":105498.0,
                        "type":"STARGATE"
                     },
                     {
                        "endpoint":"127.0.0.1",
                        "hostId":"8de68c6a-55e4-46ef-8be2-ccca39a9e9e1",
                        "dc":"datacenter1",
                        "rack":"rack1",
                        "status":"NORMAL - UP",
                        "severity":0.0,
                        "releaseVersion":"4.0.3",
                        "tokens":"18",
                        "load":93656.0,
                        "type":"CASSANDRA"
                     }
                  ]
               }
            },
            "totalLoad":199154.0,
            "endpointNames":[
               "127.0.0.2",
               "127.0.0.1"
            ]
         }
      ]
   }
}

• Updated the cluster visualization to display Stargate nodes differently from Cassandra nodes - Stargate nodes now appear in clue with a note on their tooltip

• Updated the node status visualization to hide details that will not be available for Stargate nodes, also added the (Stargate) label to the modal title as well as a display field called Node Type which will either be Cassandra or Stargate

• Stargate nodes will also be excluded from Node select options when creating repairs/schedules.

Fixes #1145

It all looks great @jdonenine, thanks!
You'll need to add a proper license header to the newly created node-utils.js file so that the build can go through.

Ah the file header, gets me every time! Added in the last commit.

Finally, Stargate nodes won't appear as down anymore 🤗
Thanks @jdonenine !
