Add ILA API and API test plugin VPP-412
The ILA plugin could only be configured through CLI. This patch adds API support to ila_interface and ila_add_del_entry functions. The patch also adds a test plugin for vpp_api_test. Change-Id: I35d96c4e56bb32862cd08cc86a9fa25ff56ef583 Signed-off-by: Pierre Pfister <ppfister@cisco.com>
