[Question] No Translations of Nested Arrays

[qwordy]

Why do you need this feature? There is No Translations of Nested Arrays. JSON is hard to use.

Is your feature request related to a problem? Please describe.

A snippet of request body

"secrets": [
            {
              "sourceVault": {
                "id": "/subscriptions/{subscription-id}/resourceGroups/ConstosoRG/providers/Microsoft.KeyVault/vaults/{keyvault-name}"
              },
              "vaultCertificates": [
                {
                  "certificateUrl": "https://{keyvault-name}.vault.azure.net:443/secrets/ContosoCertificate/{secret-id}"
                }
              ]
            }
          ]

Generated parameter definition for it

        c.argument('secrets', type=validate_file_or_dict, help='Specifies set of certificates that should be installed '
                   'onto the role instances. Expected value: json-string/@json-file.', arg_group='Os Profile')

I find that if the property has nested arrays, then autorest will define it as a string. Users need to pass the JSON string to it. It is super hard for users to input JSON string in terminal because " should be escaped in order to pass the " character. For example,

az cloud-service create --name "{cs-name}" --location "westus" --configuration "{ServiceConfiguration}" \
--extensions "[{\\"name\\":\\"RDPExtension\\",\\"properties\\":{\\"type\\":\\"RDP\\",\\"autoUpgradeMinorVersion\\":fals\
e,\\"protectedSettings\\":\\"<PrivateConfig><Password>{password}</Password></PrivateConfig>\\",\\"publisher\\":\\"Micro\
soft.Windows.Azure.Extensions\\",\\"settings\\":\\"<PublicConfig><UserName>UserAzure</UserName><Expiration>10/22/2021 \
15:05:45</Expiration></PublicConfig>\\",\\"typeHandlerVersion\\":\\"1.2.1\\"}}]" --load-balancer-configurations \
"[{\\"name\\":\\"contosolb\\",\\"properties\\":{\\"frontendIPConfigurations\\":[{\\"name\\":\\"contosofe\\",\\"properti\
es\\":{\\"publicIPAddress\\":{\\"id\\":\\"/subscriptions/{subscription-id}/resourceGroups/ConstosoRG/providers/Microsof\
t.Network/publicIPAddresses/contosopublicip\\"}}}]}}]" --package-url "{PackageUrl}" --roles \
"[{\\"name\\":\\"ContosoFrontend\\",\\"sku\\":{\\"name\\":\\"Standard_D1_v2\\",\\"capacity\\":1,\\"tier\\":\\"Standard\
\\"}}]" --upgrade-mode "Auto" --resource-group "ConstosoRG"

What is the best practice for this kind of property when using autorest?
