User story

**When using the Engines Rest API, I want to use an API Key so that authorizing my requests becomes straightforward.

Background

Today, users can use the identity service to authorize requests. For that to work, the request needs to send a header with credentials. It is noteworthy that OOB, the HTTP Basic Authentication does not provide encryption and requires the user to secure the request, i.e. via a SSL connection.

Acceptance criteria

• I can use an API key to authorize my Rest requests
