Adding new SRIOV Standalone Context
This patch adds new SRIOV context to run VNFs with - random uuid generation, - mac address generation, - getting dpdk_nic_bind path, - ssh key based authentication, - printing log messages, - added apache2 licence JIRA: YARDSTICK-480 Change-Id: Ic8317eb9e7e4ecf270091c18be4782d1299ff087 Signed-off-by: Neha Vadnere <neha.r.vadnere@intel.com> Signed-off-by: Bindya N <bindya.narayan@intel.com>
