oc import-image cannot import image from insecure docker registry

[wanghaoran1988]

When using oc import-image to import imagestream from a insecure docker registry, it will hang a very long time,and cannot import successfully, I think what we need to do is to add a option for this command like --insecure, and when create imagestream , if this option exists , and the openshift.io/insecureRepository=true automatically to the imagestream.

This falls under @pweil-'s team.

The long timeout is probably fixed by #6418

not sure... I left timeouts long for oc operations... my PR just addressed server-side clients

client side waits until the server side indicates success or failure.
