Support filtering by "Authors" in the "Packages()" Nuget query

Currently, Artifactory does not support filtering by the "Authors" property in the "Packages()" NuGet query.

Artifactory supports filtering with all other properties for this query except this one.

This filter only succeeds on remote NuGet repositories, on local and virtual it fails with 500 error.

Example:

curl http://artifactory_url:port/artifactory/api/nuget/nuget/Packages()?$orderby=Published%20desc&$skip=0&$top=80&$filter=Authors%20eq%20%27Microsoft%27

This returns the following error:

{

  "errors" : [

{     "status" : 500,     "message" : "java.lang.IllegalArgumentException: No getter found for propertyName Authors"   }

]

}
