Revert "docker-cmd hook switch to the paunch library"
This reverts commit 33241a84c1
The requirements check fails since
Ia4e086162e65a51af417a8b381ae898c95966a09 removed paunch as valid
dependency.
Since Paunch is retired, this patch propose to switch to use docker cli
for docker cmd hook and remove any dependency to Paunch.
