[UIFe] Remove Ubuntu Pro settings

[Robert Ancell]

Due to backend delay, we want to remove the Ubuntu Pro settings and only show Livepatch settings as were previously shown. This feature will be re-added at a future time.

This change will rename the "Ubuntu Pro" page to "Livepatch" and hide various UI elements. This adds the following new strings for translations:
"This machine is not covered by an Ubuntu Advantage subscription."
"Ubuntu Advantage subscription attached."
"Livepatch"

All existing strings for the Ubuntu Pro settings remain, so should remain translated when this change is reverted.

See below for screenshots of the change.

Note to self to update the PPA with this change re-enabled once this lands.

Sebastien subscribed me to this bug, but I'm not sure why. Robert has already posted about it to the ubuntu-translators list. The feature is not mentioned in Ubuntu Desktop Guide.

[Sebastien Bacher (seb128)]

Sorry for the confusion Gunnar, I was unsure if the documentation was covering that and I wrongly remembered that UIFe report needed a +1 from the translators/documentation team to be accepted

[Brian Murray (brian-murray)]

I approve of this change past UI Freeze.
