Query templates for iroha json query CLI command

[s8sato]

Would it make sense to give some query templates for iroha json query CLI command? For example, what used to be FindTransactionByHash before #5025 would be:

{
  "Iterable": {
    "query": {
      "FindTransactions": {
        "query": null,
        "predicate": {
          "Atom": {
            "Value": {
              "Hash": {
                "Atom": {
                  "Equals": "EB7A8C4C6C1C652EE8929D140EDFD844D35BDEAE8CCB0A44CB307E2C43604BE7"
                }
              }
            }
          }
        },
        "selector": [
          {
            "Atom": null
          }
        ]
      }
    }
  }
}
