Use JMESPath instead of JSONPath for response filtering

JSONPath is widely used but behaviour varies between implementations.

JMESPath has consistent official implementations in multiple languages.

JMESPath is far more capable. For example JSONPath cannot pull fields out of nested objects like this:

Response:

[  {    "id": 123,    "category": {      "id": 1,      "name": "dog"    },    "name": "Rover"  },  {    "id": 456,    "category": {      "id": 1,      "name": "fish"    },    "name": "fishy"  }]

JMESPath filter: [].{name:name,category:category.name}

Result:

[  {    "name": "Rover",    "category": "dog"  },  {    "name": "fishy",    "category": "fish"  }]

Thanks
