[sahara-image-elements] integer expression expected error

[Denis Egorenko]

During building image for Vanilla 1 with CentOS occured some error:

/tmp/in_target.d/post-install.d/40-setup-hadoop: line 56: [: 6.6: integer expression expected

It's because here:
https://github.com/openstack/sahara-image-elements/blob/master/elements/hadoop/post-install.d/40-setup-hadoop#L56
expected integer value

    Fix check distro version for hadoop setup

    It fails because now condition contains integer value,
    but for CentOS or RHEL 'lsb_release -rs' gets version
    with floating point.
    The simple way to avoid this situation is adding check for
    fedora distro.
