Description of problem:

If you encounter a problem with a repo, subscription-manager suggests disabling the repo using yum-config-manager which is not installed by default on a RHEL7.0 server and cannot be installed without disabling the problem repo.


Version-Release number of selected component (if applicable):
[root@localhost ~]# rpm -q subscription-manager
subscription-manager-1.13.19-1.el7.x86_64
[root@localhost ~]# uname -a
Linux localhost.localdomain 3.10.0-123.el7.x86_64 #1 SMP Mon May 5 11:16:57 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux
[root@localhost ~]#

How reproducible:


Steps to Reproduce:
1. Simulate broken repo

2. yum update
Loaded plugins: product-id, subscription-manager

Trying other mirror.

 One of the configured repositories failed (Red Hat Enterprise Linux 7 Server - Extended Update Support (RPMs)),
 and yum doesn't have enough cached data to continue. At this point the only
 safe thing yum can do is fail. There are a few ways to work "fix" this:

     1. Contact the upstream for the repository and get them to fix the problem.

     2. Reconfigure the baseurl/etc. for the repository, to point to a working
        upstream. This is most often useful if you are using a newer
        distribution release than is supported by the repository (and the
        packages for the previous distribution release still work).

     3. Disable the repository, so yum won't use it by default. Yum will then
        just ignore the repository until you permanently enable it again or use
        --enablerepo for temporary usage:

            yum-config-manager --disable rhel-7-server-eus-rpms

     4. Configure the failing repository to be skipped, if it is unavailable.
        Note that yum will try to contact the repo. when it runs most commands,
        so will have to try and fail each time (and thus. yum will be be much
        slower). If it is a very temporary problem though, this is often a nice
        compromise:

            yum-config-manager --save --setopt=rhel-7-server-eus-rpms.skip_if_unavailable=true

failure: repodata/repomd.xml from rhel-7-server-eus-rpms: [Errno 256] No more mirrors to try.

Actual results:

we are told to:
 yum-config-manager --disable rhel-7-server-eus-rpms

but that is not installed by default on a RHEL7.0 server

Expected results:
suggest use something known to be installed:
subscription-manager repos --disable=rhel-7-server-eus-rpms
