Fix stack environment if host ip changed

Registered by Zhenzan Zhou on 2015-08-14

In dhcp environment, devstack host ip address may change when ip renew happened. Sometimes we don't want to run unstack.sh and then stack.sh to recreate the environment. This bp will add a helper script to stop services, modify related config files and db with new IP and then restart services so we can keep the previous environment.
