<#
.SYNOPSIS
Retrieves the localized string data based on the machine's culture.
Falls back to en-US strings if the machine's culture is not supported.
.PARAMETER ResourceName
The name of the resource as it appears before '.strings.psd1' of the localized string file.
For example:
For WindowsOptionalFeature: MSFT_WindowsOptionalFeature
For Service: MSFT_ServiceResource
For Registry: MSFT_RegistryResource
For Helper: SqlServerDscHelper
.PARAMETER ScriptRoot
Optional. The root path where to expect to find the culture folder. This is only needed
for localization in helper modules. This should not normally be used for resources.
.NOTES
To be able to use localization in the helper function, this function must
be first in the file, before Get-LocalizedData is used by itself to load
localized data for this helper module (see directly after this function).

.PARAMETER CommonName
When specified, a CommonName overrides theUsed by the xADUser cmdletReturns the Identity as the Name key. For example, the Get-ADUser, Set-ADUser and
Remove-ADUser cmdlets take an Identity parameter, but the New-ADUser cmdlet uses the
Name parameter.
.PARAMETER UseNameParameter
Returns the Identity as the Name key. For example, the Get-ADUser, Set-ADUser and
Remove-ADUser cmdlets take an Identity parameter, but the New-ADUser cmdlet uses the
Name parameter.
.EXAMPLE
$getADUserParams = Get-CommonADParameters @PSBoundParameters
Returns connection parameters suitable for Get-ADUser using the splatted cmdlet
parameters.
.EXAMPLE
$newADUserParams = Get-CommonADParameters @PSBoundParameters -UseNameParameter
Returns connection parameters suitable for New-ADUser using the splatted cmdlet
parameters.
