Add function to upload image from local/url in GUI
JIRA: YARDSTICK-782 As user, we need to upload image from local/url. If upload image from local, user need to choose local image, then we will load it to openstack. If upload image from url, we will download it and load it to openstack. Change-Id: Ia9a42fda15a1dfc91476643635343a2f77a94a6b Signed-off-by: chenjiankun <chenjiankun1@huawei.com>
