Add controller exception handling in controller manager

[saikishor]

This PR adds the exception handling in the controller manager for the most commonly used controller methods that are triggered by different controller manager services

This is a very much needed feature 😁

There would be even more methods of the controller_interface to handle, like the command_interface_configuration which could also throw exceptions (during development, giving the user some better feedback).

Sure, I can take a look. I thought so of adding it, but then as it is only the InterfaceConfiguration, which basically has a list and then the enum, that's the reason I didn't add it. The worst that could happen there is a Segmentation fault, which we cannot do anything anyway.

The problem is this is present in many lines and I don't know if it is worth it.
