[network] task: added apiNodeStatus field

[AnthonyLaw]

What was the issue?

• Add symbol node's apiNodeStatus field in symbolnodes.json files

What's the fix?

• added a few methods in symbol client,
• rest version, node health, and verify wss and https status.

Expected output:

{
    "apiNodeInfo": {
      "isHealth": true,
      "isHttpsEnable": true,
      "isWssEnable": true,
      "restVersion": "2.4.2"
    },
    "extraData": {
         ...existing filed
    },
    ....existing field
  },

please change the import to import websocket and this into websocket.create_connection
(name is pretty generic, so it's nicer to use module-qualified name here)
