This patch removes IP migration and OVSDB services to promote timing 
dependency, which occurs at the master / slave exchange time and may not 
be user-configurable.
If this dependency requires upper-level processing, not every cluster 
program can easily handle it. For example, building an OVSDB cluster 
using K8S is difficult to handle this dependency.
