Removes yum packages

# Remove a yum package via exec, this is done this way because
# package { 'foo': ensure  => purged; } keeps getting called on every
# puppet run. We can't use ensure => absent because of an issue with
# circular dependencies

define yum::remove(
    $package    = $name,
    $ensure     = 'absent') {

    if ($ensure in ['absent', 'purged']) {
