REST_API: rest api client implementation
JIRA: SAMPLEVNF-78 This patch implements rest api's for VNF clients. This comprises of * vnf api's for common functionality * vnf api's for CGNAPT * vnf api's for VFW Change-Id: I56d22c64bf3ee5b0a2e536da8169ac7583499041 Signed-off-by: Vishwesh M Rudramuni <vishwesh.m.rudramuni@intel.com>
