Add more than one check in the check_eva.py

[jcassemiro]

Hi.
In the first, thanks for the code check_eva.
I have a question for configuration of check_eva.py: Can i configure this check_eva.py with two or more "checks"? Example: mode = "check_systems" and "check_controllers"? If not, how i can do this?

Regards.
