<#
    .SYNOPSIS
        Initializes SQL Reporting Services.
 
    .PARAMETER InstanceName
        Name of the SQL Server Reporting Services instance to be configured.
 
    .PARAMETER DatabaseServerName
        Name of the SQL Server to host the Reporting Service database.
 
    .PARAMETER DatabaseInstanceName
        Name of the SQL Server instance to host the Reporting Service database.
 
    .PARAMETER ReportServerVirtualDirectory
        Report Server Web Service virtual directory. Optional.
 
    .PARAMETER ReportsVirtualDirectory
        Report Manager/Report Web App virtual directory name. Optional.
 
    .PARAMETER ReportServerReservedUrl
        Report Server URL reservations. Optional. If not specified,
        'http://+:80' URL reservation will be used.
 
    .PARAMETER ReportsReservedUrl
        Report Manager/Report Web App URL reservations. Optional.
        If not specified, 'http://+:80' URL reservation will be used.
 
    .PARAMETER UseSsl
        If connections to the Reporting Services must use SSL. If this
        parameter is not assigned a value, the default is that Reporting
        Services does not use SSL.
 
    .PARAMETER SuppressRestart
        Reporting Services need to be restarted after initialization or
        settings change. If this parameter is set to $true, Reporting Services
        will not be restarted, even after initialization.
 
    .PARAMETER Encrypt
        Specifies how encryption should be enforced. There are currently no
        difference between using `Mandatory` or `Strict`.
 
    .NOTES
        To find out the parameter names for the methods in the class
        MSReportServer_ConfigurationSetting it's easy to list them using the
        following code. Example for listing
 
        ```
        $methodName = 'ReserveUrl'
        $instanceName = 'SQL2016'
        $sqlMajorVersion = '13'
        $getCimClassParameters = @{
            ClassName = 'MSReportServer_ConfigurationSetting'
            Namespace = "root\Microsoft\SQLServer\ReportServer\RS_$instanceName\v$sqlMajorVersion\Admin"
        }
        (Get-CimClass @getCimClassParameters).CimClassMethods[$methodName].Parameters
        ```
 
        Or run the following using the helper function in this code. Make sure
        to have the helper function loaded in the session.
 
        ```
        $methodName = 'ReserveUrl'
        $instanceName = 'SQL2016'
        $reportingServicesData = Get-ReportingServicesData -InstanceName $InstanceName
        $reportingServicesData.Configuration.CimClass.CimClassMethods[$methodName].Parameters
        ```
 
        SecureConnectionLevel (the parameter UseSsl):
        The SecureConnectionLevel value can be 0,1,2 or 3, but since
        SQL Server 2008 R2 this was changed. So we are just setting it to 0 (off)
        and 1 (on).
 
        "In SQL Server 2008 R2, SecureConnectionLevel is made an on/off
        switch, default value is 0. For any value greater than or equal
        to 1 passed through SetSecureConnectionLevel method API, SSL
        is considered on..."
