Processed metrics metadata 

They appear in normal API output, see https://github.com/piwik/piwik/blob/master/tests/PHPUnit/System/expected/test_OneVisitorTwoVisits__Actions.getEntryPageUrls_day.xml .

They were not specified in metadata classes so did not appear in API.getProcessedReport. Please specify whether they should be removed from the Actions API as well. If not, they should stay in this output.
