New OMS query setup

[CharlPels]

The current sample seems to use the old querys

example
Type=Alert (AlertSeverity=error or AlertSeverity=critical) TimeGenerated>NOW-24HOUR AlertState!=Closed

should now be something like this
Alert | where (AlertSeverity =~ "error" or AlertSeverity =~ "critical") and TimeGenerated > ago(24h) and AlertState != "Closed"

this however is not working like it should in current powershell code
