This patch is fix a regex of naming rule for a Pod of a Deployment.
The naming rule of Pod in deployment is
"(deployment name)-(pod template hash)-(5 charactors)".
Currently, "pod template hash" is a regex with a fixed 10 characters.
However, it may be less than 10 characters, this case is fail in
"scale_wait" of CNF scale.
The "pod template hash" string is generated from 32 bit hash. This
may be from 1 to 10 caracters but not sure the lower limit from the
source code of Kubernetes. Temporarily, this is set to be "{1,10}"
but may need to be fixed.
