Use Dynamic Parameters for Roles

[mapresto]

Is your feature request related to a problem? Please describe.
There are multiple functions that reuses the same validateset for parameters. A dynamic parameter can allow for a single source of updating for this.

Describe the solution you'd like
Something close to below:

DynamicParam {
                # Set the dynamic parameters' name
                $ParameterName = "Role"

                # Create the dictionary 
                $RuntimeParameterDictionary = New-Object System.Management.Automation.RuntimeDefinedParameterDictionary

                # Create the collection of attributes
                $AttributeCollection = New-Object System.Collections.ObjectModel.Collection[System.Attribute]
            
                # Create and set the parameters' attributes
                $ParameterAttribute = New-Object System.Management.Automation.ParameterAttribute
                $ParameterAttribute.Mandatory = $true

                # Add the attributes to the attributes collection
                $AttributeCollection.Add($ParameterAttribute)

                # Generate and set the ValidateSet 
                $roleSet = Import-CSV C:\Users\mapresto\desktop\DynamicParamTest\Roles.csv -Header Role | Select -ExpandProperty Role
                $ValidateSetAttribute = New-Object System.Management.Automation.ValidateSetAttribute($roleSet)

                # Add the ValidateSet to the attributes collection
                $AttributeCollection.Add($ValidateSetAttribute)

                # Create and return the dynamic parameter
                $RuntimeParameter = New-Object System.Management.Automation.RuntimeDefinedParameter($ParameterName, [string], $AttributeCollection)
                $RuntimeParameterDictionary.Add($ParameterName, $RuntimeParameter)
                return $RuntimeParameterDictionary
        }

        Begin
        {
            $Role = $PSBoundParameters[$ParameterName]
        }

        Process {}

Roles have been largely standardized in 2.0. For public functions, roles.csv is filling a dynamic parameter for the function.
