Subject: [PATCH] stack.sh: Clear OpenStack related envvars

stack.sh usually fails when it is started in a shell session
where OpenStack related environment variables OS_* are set.
Most common failure scenarios are failures in keystone operations.

This commits clears OpenStack related environment variables
at the begining of stack.sh.
