Implement retry policy for a message delivery

[matjazv]

Description

In request/response message transferring it could occur that a request is not delivered or a response is lost because of various reasons.
Currently when a request is sent and if a response is not received a timeout occurs and an error is returned.
Implement additional feature that in case of a timeout, a request is sent again and only after configured number of retries an error is returned.

Acceptance Criteria

• If a response is not received, a request is sent again.
• Only after configured number of retries an error is returned.
• All new code is unit tested.
