Tags are no longer hashtable array

[shin-akuma]

Hi Paul,
Thanks for sharing your brilliant idea on the schedule tag. I'm using it in our Azure Sub to saving cost. However, I think you script was developed when the tags property of AzureRMReource is still hashtable array. At the moment, the tags property is just hashtable. Therefore, a few tweaks need to be made to your scripts:

function ContainsSchedule
{
	param
	(
		[Parameter(Mandatory=$false)]
		[System.Collections.Hashtable]$tags
	)

	if ($tags -eq $null)
	{
		return $false
	}

	foreach ($key in $tags.Keys)
	{
		if ($key -eq "schedule")
		{
			return $true
		}
	}

	return $false
}

function GetSchedule
{
	param
	(
		[Parameter(Mandatory=$false)]
		[System.Collections.Hashtable]$tags
	)
	
	if ($tags -eq $null)
	{
		return $null
	}

	foreach ($key in $tags.Keys)
	{
		if ($key -eq "schedule")
		{
			return $tags[$key]
		}
	}
}

-------------->
$resource = Get-AzureRmResource -Name $vmName -ResourceType "Microsoft.Compute/virtualmachines"

    foreach ($key in $resource.Tags.Keys)
    {
        if ($key -ne "schedule")
        {
            $tags.Add($key, $resource.Tags[$key])
        }
    }
    $scheduleJson = $_[1]
    $tags +=@{"schedule"=$scheduleJson}

I'm happy to create a PR if you make me contributor.

Thanks again for sharing your brilliant script and idea!
