Fedora/RHEL Installation Guide needs both RDO and EPEL

[Stephen Gordon]

In "Installation Assumptions" (http://docs.openstack.org/trunk/openstack-compute/install/yum/content/assumptions.html ) the RDO repository is enabled. This provides all of the Grizzly OpenStack packages, as it turns out however it doesn't include some of the dependencies which come from EPEL. As a result users actually need both enabled.

"""
As mentioned in the comment, had the exact same issue when following the http://docs.openstack.org/trunk/openstack-compute/install/yum/content/install-keystone.html (installation guide) on a CentOS 6.4

Adding the epel repository solved the issue:

    Download the latest epel-release rpm from:

    http://dl.fedoraproject.org/pub/epel/6/i386/

    Install epel-release rpm:

    rpm -Uvh epel-release*rpm

The http://docs.openstack.org/trunk/openstack-compute/install/yum/content/install-keystone.html (installation guide) should be updated imo

    Bug # 1198273 - Add EPEL repository to assumptions.

    Added EPEL repository to instructions and modified RDO instruction to
    use a consistent approach (using the "release" RPM). Also fixed prompt
    which erroneously indicated normal user could write to /etc/yum.repos.d.
