By default run AsciiDoc and package the documentation as part of the WAR. This ensures the default `mvn package` will include user documentation, as folks have come to expect it to exist in builds. If AsciiDoc is not available documentation can be skipped by passing -Dgerrit.documentation.skip=true on the command line. This naming convention matches with -Dmaven.test.skip=true as a way to avoid running unit tests. Change-Id: Ic433c5bb291c9abb48117d61c2eabc031a5c5ca0
