Check for underlying OS updates

[willow9886]

We should notify organizations when updates to the underlying server OS are available.

The idea is to write a script which will check whether OS updates are available, then expose a configuration option in oxTrust that allows the administrator to enable / disable notifications inside oxTrust when updates are available. If enabled, the admin can simply click a button in oxTrust to update the OS.

Tasks:

• Get list of command for each supported OS type

• Write scripts to run these commands. One script to check if there are updates, and a second script to install updates. Or, one script which supports command line options.

• Configure sudo to be allowed to run this script

Once this task is complete, we should open an issue on oxTrust repo with details to implement the admin UX.

This script automatically applies the updates. Should we just add it to the chroot and enable it? We also need instructions in the docs for how to disable it, in case customers don't want updates automatically.
