      Server should be able to determine what os/distro/platform it is running on.
      To get a better picture of what is going on "under the hood", as well as be able to provide platform-specific guidance in regards to particular operating systems/distributions, we should have a method of reporting back these bits of information.
      Possibly collect them via mms_agent and report them back so we can then inspect and act on the details.

      Here's a few methods for collecting relevant information from the linux command line, and you can see there are differences. Possibly have a decision-making process to determine which method should be used to collect the rest?

      So it seems like on a *nix system, running a `uname` will provide whether it is Darwin vs Linux, and then other tests could be run to grab relevant information.

      Things I'd care about knowing:
      Distro (CentOS, RHEL, Debian, Ubuntu)
      Distro Version (6.2, 5.7, 10.04, etc)
      Architecture (i386 vs x64_86)
      Kernel version (2.6.18, 2.6.32, etc)

      Windows has a different method, using the `systeminfo` command line tool, like so:

      C:\>systeminfo | findstr /C:"OS"
OS Name:                   Microsoft Windows Server 2008 R2 Enterprise
OS Version:                6.1.7600 N/A Build 7600
OS Manufacturer:           Microsoft Corporation
OS Configuration:          Standalone Server
OS Build Type:             Multiprocessor Free
BIOS Version:              IBM -[BWE117AUS-1.05]-, 7/28/2005

      This returns too much, including the BIOS, so using a better find like this: `findstr /B /C:"OS Name" /C:"OS Version"` should get the relevant information.
