add Api Service

[JeanBarriere]

We need to create an API service, generating endpoints and returned values based on the API version
The following methods needs to be in the service.

• initialize with API version
• get method request
• post method request
• put method request
• patch method request
• delete method request
• cancel a request (in case any search request is implemented)

Some static methods also need to be present:

• get hyperMediaLinks of a return object
