Fix VCLS VM matching

[joisika]

          Maybe more like this here and in similar areas

while ($counter -ne $retries) {
    if (Test-vSphereAuthentication -server $vcfVcenterDetails.fqdn -user $vcfVcenterDetails.ssoAdmin -pass $vcfVcenterDetails.ssoAdminPass) {
        $vclsPoweredOn = (Get-VM -Location $clusterNameExtra | Where-Object { $_.name -match "vCLS" } | Measure-Object).Count
        if ($vclsPoweredOn -gt 0) {
            Write-PowerManagementLogMessage -Type INFO -Message "Some vCLS virtual machines are still running. Sleeping for $sleepTime seconds until the next check..."
            Start-Sleep -s $sleepTime
            Break
        }
    }
}

Additionally, it's termed as powered on, but the powerstate is not requested in the Where-Object. Should it be more like:

$vclsPoweredOn = (Get-VM -Location $clusterNameExtra | Where-Object { $_.name -match "vCLS" -and $_.PowerState -eq "PoweredOn" } | Measure-Object).Count

Another option is to change the scope to focus on the VMs in the "vCLS" folder instead of all VMs in the inventory that have a string match.

$vclsPoweredOn = (Get-VM -Location (Get-Folder -Name "vCLS") | Where-Object { $_.PowerState -eq "PoweredOn" } | Measure-Object).Count
