Issue DURACLOUD-460: Provide informative error messages for special characters in space and content properties
Special characters included in metadata names or values which are added to spaces or content show up immediately in the list of metadata/tags, but when those special characters aren't valid http header values, the information is not actually added to the space or content item in the provider. This task is to to check for valid characters and pass back errors to users so they know the allowable characters.
