This avoids a duplicate parse with DiscussionTools (T376325) and also reduces some redundancy by using the metrics-gathering code from ParserOutput instead of having to clone it here. Finally, it allows the parse to use the output of a previous parse for selective update. Bug: T376325 Follows-Up: I64a4556a74da4f735a5b562070c21310ecda36d1 Change-Id: I11386e307caaa9fce34870b08bd4dce4c5e6eb25
