tests: resize root partition when atomic host For a few moment we can see failures in the CI for containerized scenarios because VMs are running out of space at some point. The default in the images used is to have only 3Gb for root partition which doesn't sound like a lot. Typical error seen: ``` STDERR: failed to register layer: Error processing tar file(exit status 1): open /usr/share/zoneinfo/Atlantic/Canary: no space left on device ``` Indeed, on the machine we can see: ``` Every 2.0s: df -h Tue May 29 17:21:13 2018 Filesystem Size Used Avail Use% Mounted on /dev/mapper/atomicos-root 3.0G 3.0G 14M 100% / ``` The idea here is to expand this partition with all the available space remaining by issuing an `lvresize` followed by an `xfs_growfs`. ``` -bash-4.2# lvresize -l +100%FREE /dev/atomicos/root Size of logical volume atomicos/root changed from <2.93 GiB (750 extents) to 9.70 GiB (2484 extents).
