Request sponsorship of this upload for cosmic and then SRU to bionic
 - New debdiff uploaded for both bionic and cosmic
 - Fixed the SRU version for bionic
 - Added a comment about the workaround to the script
 - Updated bug description with SRU template

Tested patch working on bionic with my machine which consistently exhibits the issue with a package built from this diff (albeit with a 5 second delay on network interface up, hopefully after this we can switch to fixing the actual issue with host)

The key note I see on the machine I can reproduce this on (a linux bridge over an Intel I219-LM) is that both the interface route and the default route are in the 'linkdown' state when the host command fires for about 0.7 seconds total. When I looked at a different machine, that stage never happened or at least for a much shorter time (i'd have to check ip monitor again).

I don't expect anyone to reproduce this for testing, i'm happy to test the -proposed packages on an affected machine.
