Add tool to verify services health

[netoax]

The investigation of problems that appears on the gateway isn't an easy task since there are a lot of services integrated into it. The most common approach is checking the system log (by looking at the /var/log/messages file) and checking the service's logs individually by restarting them and sometimes changing their log configuration properties manually. Hence, despite having documentation describing each of these steps, it requires a certain level of technical knowledge causing this process to be almost impossible for new users.

Therefore, one solution to this could be creating a tool that generates a diagnostic report by looking for the service's logs and collecting other system's properties that can indicate the problem source.
