perf report -t output as object

just ran across "perf report -t" and wanted to be able to get the same format from powershell.

these are quick (and probably inefficient) functions that format the cpu_disk_util_matrix counter as a table like the output from "perf report -t"

cluster version returns a hash.

. .\get-naperfreport.ps1

Get-NaPerfReport -Controller <filer> | out-gridview

. .\get-ncperfreport.ps1

$results = Get-NcPerfReport -Controller <cluster>

$results.item("<node>") | out-gridview
