Subject: [PATCH] RHEL 7: Disable unsupported remote drive protocols

 (RHBZ#962113).

This disables support for unsupported remote drive protocols:

 * ftp

 * ftps

 * http

 * https

 * tftp

 * gluster

 * iscsi

 * sheepdog

 * ssh

Note 'nbd' is not disabled, and of course 'file' works.

We hope to gradually add some of these back over the lifetime of RHEL 7.

In RHEL 7.2: rbd (Ceph) support was enabled.
