Adding system info logging for Linux

[john-science]

What is the change?

Adding detailed system information for OS and processors, for a wide range of Linux operating systems.

Because there are so many different flavors of Linux, the new system info logging has multiple redundant ways to find the same OS/processor information. The code will try each one in turn before giving up and trying the next one. In this way, we should support a wide array of Linux flavors seamlessly.

Why is the change being made?

ARMI is supposed to support Windows and Linux.

I'll want to test this internally too given the runLog nature of the update. But great work!

This tested as expected!
