remove default behavior of selecting all resources
remove default behavior of selecting all resources

Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1640843

By default, all imagestream resources were selected if no arguments
were passed to the "set image-lookup" command. This patch updates
the command so that either the --all flag, or a specific set of
imagestream names must be provided in order for those resources
to be updated.
