SqlPowerShellModule: New resource proposal

Now when SqlServer module has been release to PowerShell Gallery I think we need a resource that is able to download the module from either PowerShell Gallery or from an UNC share.

This might be better as a common resource that can download any module? Is there one already?

Suggested a start to a schema to discuss from.

[ClassVersion("1.0.0.0"), FriendlyName("SqlPowerShellModule")]
class MSFT_SqlPowerShellModule : OMI_BaseResource
{
    [Write, Description("If the SqlServer module should be present on absent on the server being configured."), ValueMap{"Present","Absent"}, Values{"Present","Absent"}] String Ensure;
    [Write, Description("The path from where to copy (download) the SqlServer module. If not set the module will be downloaded from PowerShell gallery")] String Path;
    [Write, Description("If set to one or more registred repositories the module will be downloaded from one of those repositorys. If not set, then the module will be downloaded from PowerShell gallery. If parameter Path is set, this parameter will be ignored.")] String Repository[];
    [Write, Description("If this is set to $true and the same version already exists on the computer, then the downloaded module will be overwrite the existing module.")] Boolean Force;
    [Write, Description("The version that must be downloaded, if the version does not exists the resource will throw an error.")] Boolean RequiredVersion;
    [Write, EmbeddedInstance("MSFT_Credential"), Description("The credentials used to access the path set in the parameter Path. This is optional if downloading the module from a repository. This is also optional if either the SYSTEM account or the built-in PsDcsRunAsCredential has access to the path.")] String SourceCredential;
};

Parameters more easily read:

Start by resolving whether this should be a SqlPowerShellModule resource or a common resource for downloading any PowerShell module. Review the proposed Ensure, Path, Repository, Force, RequiredVersion, and SourceCredential parameters, including PowerShell Gallery and UNC-share behavior. Done means the resource scope and parameter contract are agreed and implemented with coverage for the stated download sources and version requirements.
