Description

This PR implements a refactor of the HttpClient making it a generic abstract class to handle HTTP requests which is inherited in the specific CommandManagerClient, and CTIClient classes to handle the connections to its corresponding APIs.

The endpoints were proved to keep working as they were and how it should

Unit tests were added only for the base HttpClient class, this is because I've found difficult to mock the ClusterService object required by the PluginSetting used in the rest of clients.
