REST API - Attribute option creation -> no ID returned

[radoslavdodek]

Preconditions

1. Tested in Magento version: 2.1.4

Steps to reproduce

1. Fresh install
2. Make following REST request:

POST /rest/default/V1/products/attributes/manufacturer/options

with following Body:

{
  "option": {
    "label": "Manufacturer 1"
  }
}

Expected result

One of following:

1. The response Body should contain the ID of newly created option
2. The response Header should contain the ID of newly created option

The reason is that external systems will usually remember the ID so that it can be later referenced (for example when the external system needs to delete that option later).

Actual result

1. The response body contains just following string:
   true

Same results for SOAP API, returning option id is better than returning string value.
