[sos-devel] Support for in-container detection

[Louis Bouchard]

Hello,

Following discussion in PR #893[1], I am opening the discussion on how to better
support in-container detection.

The Policy class has a _in_container variable available. As far as I can tell,
it is only used by the RedHat policy to detect Docker.

cloud-init has a rather simple container detection method that uses
systemd-detect-virt and a few other methods[2]. This could be used as a base for
such an amelioration.

My idea was to adapt the cloud-init method and use it to document _in_container
through the __init__().

Let me hear your comments.

TIA,

...Louis
