Add support for exporting and importing all entities

[jensalm]

Allow the cli to export and import all entities. The export should not contain instance specific details like ids, when it was created, etc.
The output from export should be able to be imported in an empty ziti instance.
Output should support both json and yaml.

Example:

  "identities": [
    {
      "appData": {},
      "authPolicy": "@Default",
      "disabled": false,
      "externalId": null,
      "isAdmin": true,
      "isDefaultAdmin": false,
      "isMfaEnabled": false,
      "name": "Test 1",
      "roleAttributes": [],
      "tags": {},
      "typeId": "Default"
    }
  ],
  "configs": [
    {
      "data": {
        "addresses": [
          "google.ziti"
        ],
        "portRanges": [
          {
            "high": 120,
            "low": 80
          }
        ],
        "protocols": [
          "tcp"
        ]
      },
      "name": "test 1 intercepting config",
      "tags": {},
    }
  ]
  "services": [
    {
      "configs": [
        "@test 1 intercepting config"
      ],
      "encryptionRequired": true,
      "name": "test 1",
      "roleAttributes": [
        "services"
      ],
      "tags": {},
      "terminatorStrategy": "smartrouting"
    }
  ]

What's an example use case for the feature? By recreate do you mean clone to a fresh network as opposed to managing a Ziti network's entities?

Basic use case is to be able to "clone" a network.
