From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

When pushing a pseudo reference (such as "refs/for/master/topic"), may
create or update one or more references.  The real names of the
references will be stored in the report options.  Parse report options
to create or update remote-tracking branches properly.
