Enhancement Invoke-IcingaCheckCPU: add a "top cpu-users" to output

[tectumopticum]

You often hear the question which process triggers the cpu-usage-events. After login to the server the high-load-situation is often over and you don't have appropriate information how to avoid this in the future.
So ist would be nice to add something like

Get-Process | Sort-Object -Property 'CPU' -Descending | Select-Object -First 3
(easy code, but only cpu-usage-time in seconds)

get-wmiobject Win32_PerfFormattedData_PerfProc_Process| Select-Object -Property Name, IDProcess, HandleCount, PercentProcessorTime | Sort-Object -Property 'PercentProcessorTime' -Descending | Select-Object -First 5

....or other better suggestions...

to the output of the plugin if one of the triggerlevels is reached.
Maybe it makes sense to connect this to the verbosity-level.
