    Update allowed_hosts conditional statement

    In the origin cinder::db::mysql, if the value of $allowed_hosts
    contains or equals to $host, then puppet will complain duplicate
    declaration error. This patch is aim to update the allowed_hosts
    conditonal statement in cinder::db::mysql.

    There are two cases to pass $allowed_hosts to $real_allowed_hosts:

       - If $allowed_hosts is array,then remove $host from $allowed_hosts;
       - elsif $allowed_hosts is string and not equivalent to $host;

    At last, if $real_allowed_hosts is not undef, then run
    cinder::db::mysql::host_access

    Fix bug 1206444
