BUG: racadm remoteimage vs xml import

There's a bug in consistency between using HTTP as the remote share to assign a remoteimage vs importing an SCP XML file.

`racadm remoteimage' allows you to use http://server:port/ to specify a remote URL

However, `racadm set' to import an SCP XML file via http://server:port/ does not use the specified port and defaults to port 80.  If you specify a port other than 80, it does not return an error, either.  It will give the vague SYS046 error which doesn't indicate the true root cause.
