package epel-release-7-8 is not installed

[sven mark]

When installing MapR into a cluster on CentOS 7, the plugin tries to download epel release version 7-8 from the url http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm.

This release version is not available anymore and should be replaced with epel-release-7-9 on the url rpm -i http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-9.noarch.rpm

bug https://bugs.launchpad.net/sahara/+bug/1615761 is because 7-5，why can not replace with yum install -y epel-release to solve the problem permanently in /opt/stack/sahara/sahara/plugins/mapr/resources/add_mapr_repo.sh(31) with:

    release=`cat /etc/*-release`
    if [[ $release =~ 6\.[0-9] ]]; then
        rpm -q epel-release-6-8 || \
            rpm -i http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
    elif [[ $release =~ 7\.[0-9] ]]; then
        rpm -q epel-release-7-8 || \
            rpm -i http://download.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-8.noarch.rpm
    else
        echo "Unsupported distribution version"
        exit 1
    fi

    RHEL: fix distro detection and EPEL configuration

    Distribution detection was working and it probably broke with RHEL 7.4.
    This issue affects at least the MapR plugin, which installs few packages
    at run-time and it fails to find the distribution.
    A new field was added (internal_name) and used only for the comparison
    because the 'name' proprty is used as parameter in other scripts and
    changing it would touch a lot of code.

    Also, fix the installation of EPEL repository, which was fixed
    some time ago (from Pike) so that it did not depend on a specific
    hardcoded version, but the fix worked only on CentOS, not on RHEL
    where the epel-release package is not available.
