Adding Check for Clusterhealthcheck if this is really a ClusterNode

[Wintermute2k6]

Installing the component on a non valid Cluster node and trying to execute the check ends in abrupt break and there seems to be no real error message.

Suggestion adding the following

function Invoke-IcingaCheckClusterHealth()
{
    param (
        [array]$Include               = @(),
        [array]$Exclude               = @(),
        [ValidateSet('Unknown', 'Up', 'Down', 'Paused', 'Joining')]
        [array]$WarningState          = @(),
        [ValidateSet('Unknown', 'Up', 'Down', 'Paused', 'Joining')]
        [array]$CriticalState         = @(),
        [switch]$SkipClusterRessource = $FALSE,
        [switch]$NoPerfData           = $FALSE,
        [ValidateSet(0, 1, 2, 3)]
        $Verbosity                    = 0
    );

    if((Get-WindowsFeature -Name Failover-Clustering).InstallState -eq "Available") {
       Write-IcingaEventMessage -EventId xxxx -Namespace 'Cluster';
       echo "This is not a vaild Failover cluster node this component shouldn't be installed here"
       break;
      }
      else {
        continue;
      }

    # Create a main CheckPackage under which all other checks will be placed
    $CheckPackage       = New-IcingaCheckPackage -Name 'Cluster Services' -OperatorAnd -Verbose $Verbosity -AddSummaryHeader;
    $ClusterServiceInfo = Get-IcingaClusterInfo;
