Description of problem:
As per Section 7.11 of the RBD guide, In the RHCS 4, we should be able to install the ceph-iscsi-tools package that provides the "gwtop" command for monitoring purposes.
But when we try to install it, it failed with the following output:

~~~
No package ceph-iscsi-tools available.
Error: Nothing to do
~~~
- It seems like the package is missing. Is this an expected behavior? And what is the best way to install the package?

In RHCS 3, I am able to install it smoothly.
Version-Release number of selected component (if applicable): RHCS 4.2


Steps to Reproduce:

1. On the iscsiGW node, enable the RHCS 4 repos using the command:
$ subscription-manager repos --enable=rhel-7-server-rhceph-4-mon-rpms --enable=rhel-7-server-rhceph-4-osd-rpms --enable=rhel-7-server-rhceph-4-tools-rpm

2. Install the ceph-iscsi-tools package:
$ yum install ceph-iscsi-tools -y


Actual results:
- No such package is available to install


Expected results:
- It should install the ceph-iscsi-tools package successfully and provide the command "gwtop"
