CLI definition export incorrectly serialises federation upstreams about rabbitmq-cli

[michaelklishin]

This is how parameters in the problematic case are deserialised:

"parameters" => [
     %{
       "component" => "federation-upstream",
       "name" => "up-1",
       "value" => [
         ["ack-mode", "on-confirm"],
         ["trust-user-id", false],
         ["uri", "amqp://127.0.0.1:5672"]
       ],
       "vhost" => "/"
     },
     %{
       "component" => "shovel",
       "name" => "shovel-60",
       "value" => [
         ["ack-mode", "on-confirm"],
         ["dest-add-forward-headers", false],
         ["dest-protocol", "amqp091"],
         ["dest-queue", "shovel-60-dst"],
         ["dest-uri", "amqp://localhost:5672"],
         ["src-delete-after", "never"],
         ["src-protocol", "amqp091"],
         ["src-queue", "shovel-60-src"],
         ["src-uri", "amqp://localhost:5672"]
       ],
       "vhost" => "/"
     }
   ]

JSON file difference makes it clear it's an export_definitions issue:

"parameters": [
        {
            "component": "federation-upstream",
            "name": "up-1",
            "value": [
                [
                    "ack-mode",
                    "on-confirm"
                ],
                [
                    "trust-user-id",
                    false
                ],
                [
                    "uri",
                    "amqp://127.0.0.1:5672"
                ]
            ],
            "vhost": "/"
        },

                [
                    "dest-uri",
                    "amqp://localhost:5672"
                ],
                [
                    "src-delete-after",
                    "never"
                ],

                [

                    "amqp://localhost:5672"
                ]
            ],
            "vhost": "/"
        }
    ],

vs. HTTP API-produced one:

        {
            "value": {
