Feature Request - Make Invoke-IcingaCheckMSSQLPerfCounter usable with Raw Value Performance Counters

[audiocoach]

There are a lot sql performance counters which are displayed in raw values by default. For example Batch Requests/sec. If you query them via Invoke-IcingaCheckMSSQLPerfCounter which infact uses the follwoing sql query the output is a raw value

SELECT
    RTRIM(object_name) as object_name,
    RTRIM(counter_name) as counter_name,
    RTRIM(instance_name) as instance_name,
    RTRIM(cntr_value) as cntr_value,
    RTRIM(cntr_type) as cntr_type
        FROM sys.dm_os_performance_counters
WHERE (object_name LIKE '%:SQL Statistics%' AND counter_name = 'Batch Requests/sec');

It would be greate to implement some logic to get the cooked value for those performance counters. Maybe it is possible to fetch the cntr_type and if it is 272696576 (=PERF_COUNTER_BULK_COUNT) calculate the cooked value.
