There are many params across the whole API with invalid type validators. This is producing invalid types in API description which has impact on option validation in CLI.

For example, there is :architecture_id in the hostgroup controller using :number as a type instead of Numeric or Integer

  param :architecture_id, :number, :desc => N_('Architecture ID')

producing documentation with invalid expected_type

                  {
                    "name": "architecture_id",
                    "full_name": "hostgroup[architecture_id]",
                    "description": "\n\u003cp\u003eArchitecture ID\u003c/p\u003e\n",
                    "required": false,
                    "allow_nil": true,
                    "allow_blank": false,
                    "validator": "number.",
                    "expected_type": "string",
                    "metadata": null,
                    "show": true,
                    "validations": []
                  },

While documenting params in the API documentation we should use only valid type Validators [1]².
