ONE-4: Add LISP enable/disable API/CLI
This patch adds an enable/disable API/CLI for control plane which calls similar functions for data plane. When re-enabling it also re-populates dataplane with tunnels and interfaces. Change-Id: Id8c3d6af90ecc0be331d502756914b1f62824046 Signed-off-by: Filip Tehlar <ftehlar@cisco.com>
