    .SYNOPSIS
    Configures the Maintenance window for the provided Cloud Director Service instance.

    .DESCRIPTION
    Configures the weekly 2-hour maintenance window during which VMware checks if the VMware Cloud Director instance is eligible for upgrade and upgrade it if it is the case.
    
    The maintenance window Start Time/Day is set in UTC.

    .PARAMETER InstanceId
    The Cloud Director Instance Id

    .PARAMETER InstanceName
    The Cloud Director Instance Name

    .PARAMETER EnvironmentId
    Optionally The Cloud Director Service Environment Id (Default is used if none is provided)

    .PARAMETER MaintenanceDay
    The Maintenance Window Day (e.g. Sunday)
    Please Note: The maintenance window Start Time/Day is set in UTC.

    .PARAMETER MaintenanceStartTime
    The Maintenance Start Time Hour (UTC) as an Integer (e.g. 0 = 00:00, 13 = 13:00).
    Please Note: The maintenance window must start on the hour (e.g. 01:00 or 23:00) and duration will be 2 hours from the start time.

    .PARAMETER SkipNextWindow
    If this flag is set the VMware Cloud Director instance is excluded from the current week's scheduled maintenance window

    .EXAMPLE
    Set-VCDSInstanceMaintenance -InstanceName "CloudDirector-TestInstance-01" -MaintenanceDay "Friday" -MaintenanceStartTime 9
    Sets the maintenance window for the instance named "CloudDirector-TestInstance-01" to commence weekly on Friday at 9:00 - 11:00 UTC

    .EXAMPLE
    Set-VCDSInstanceMaintenance -InstanceName "CloudDirector-TestInstance-01" -SkipNextWindow
