We use "uname -a" to check the distro in multiple places in the code. I am concerned with updating only this one instance.

Actually, maybe we should use get_distro(), in the Agent's code to do this

Updated to use get_distro to get distro name and version for all test suites which use "uname -a"

get_distro.py produces _ and here we are only using the name ("flatcar")

We check if any of these are a substring in the result of get_distro.py. This check is on Line 45

If we only put distro name in this list, then we know that extension doesn't support any version of the distro. If we put 'name_version' then we can mark that the extension only excludes a certain version. I did this since mariner_1 is unsupported by AMA, but mariner_2 is supported
