commit 969bbfd06476a71f66882964e5ea92b0bebbcc5b

stonith: Check for missing params in new device and dup
    
    device_has_duplicate would return a dup if all params in device where in dup with the same value but
    if dup had a param that device did not the dup would still be considered a duplicate. This updates
    the duplicate check to make sure that all keys and values overlap in both device and dup params.
