PSAvoidUsingUserNameAndPasswordParams should not flag boolean/switch type password parameter

[kapilmb]

For the following code snippet in a file called test1.ps1

function foo
{
    param(
    [string] $Username,
    [switch] $HidePassword
    )
}

PSScriptAnalyzer trips PSAvoidUserNameAndPasswordParams.

                                                                  of type PSCredential. If using a Credential         
                                                                  parameter in PowerShell 4.0 or earlier, please

                                                                  the PSCredential type attribute. 

In this case $HidePassword is clearly not intented to pass the password parameter and hence, this rule should ignore it.
