Bugfix: Bad substitution wthen run shell script

When run yardstick-get-k8s-conf.sh, there is an error:
    /tmp/hudson2171423090360971912.sh: 6:
    /tmp/hudson2171423090360971912.sh: Bad substitution

To solve this problem, we need set using /bin/bash to run script.
If we do not set it, it will using /bin/sh by default.
