Feature Request: Add handling for HAL responses

[swright-eti]

Our REST APIs respond with either application/hal+json or application/problem+json. Would it be possible to add these response types as something that OpenBlocks understands? That way I dont have to have a transformer for all the responses.

Here is a doc from Spring about this: https://docs.spring.io/spring-hateoas/docs/current/reference/html/

Nice request🤩, so what do you expect to achieve, could you describe it more specifically, very appreciate that

When OpenBlocks gets a response from an API and that response is one of application/hal+json or application/problem+json then the response body should be kept as JSON.

What happens now is that OpenBlocks treats the body of the response as an escaped JSON String. That means that for every response I need to have a Transformer to convert it back to JSON. If you look at the following image you can see that there is an array of devices on the path _embedded.devices. If I try to access that with {{get_device_list.data._embedded.devices}} it will fail with "undefined" because get_device_list.data does not contain JSON, it contains an escaped JSON string.

Adding the ability for OpenBlocks to handle HAL responses would extend or match the current behavior when the response is application/json.

I have tested this and it works. Thank you.
