To measure the time to pod network, a deployment that uses agnhost image is used, which get exposed as a net server and replies to curl calls, the test measure this reply time and saves it for further reporting. Then, only the exposed net service gets deleted. Signed-off-by: Morales Quispe, Marcela <marcela.morales.quispe@intel.com>
