Run atop for monitoring deployment

Use atop[1] tool to monitor the whole job process.
Atop generates binary output that could be downloaded
and then investigated locally.
Using atop -r /path/to/atop.bin you can read the file
and by pressing "t" to move 10 seconds futher or by
pressing "b" to jump to specific time in job and to see
what happened on host in this time. It allows to track
all resources in specific time.
It allows also tracking of containers separately.
For more info you can visit the site[1]
If atop installation fails it shouldn't fail the job,
so ignore_errors is added.
Currently it's for undercloud in OVB and all nodes in
multinode.
