Clear-MofAuthoringMetadata

Everytime PowerShell generates a .mof file, it includes authoring metadata: who created the file, on what computer, and at what date/time. This means a .mof file's checksum will change everytime a new one is generated, even if the configuration in that file didn't change. This makes it hard to know when a configuration in a .mof file has truly changed, and makes its change history noisy. This function strips/removes all authoring metadata from a .mof file.

When given a path to a file, all authoring metadata is removed from that file. When given the path to a directory, removes authoring metadata from all *.mof files in that directory.

Essentially, these blocks from each .mof file:

/*
@TargetNode='********'
@GeneratedBy=********
@GenerationDate=08/19/2014 13:29:15
@GenerationHost=********
*/

/* ...snip... */


instance of OMI_ConfigurationDocument
{
 Version="1.0.0";
 Author="********;
 GenerationDate="08/19/2014 13:29:15";
 GenerationHost="********";
};

Would be changed to:

/*
@TargetNode='JSWEB01L-WHS-08'
*/

/* ...snip... */

instance of OMI_ConfigurationDocument
{
 Version="1.0.0";
};

Clear-MofAuthoringMetadata is new in Carbon 2.0.
