bisect: set HG_NODE when runing a command

When running a command, set the environment variable HG_NODE to
tell the command which changeset is being visited.

    As a shortcut, you can also use the revision argument to mark a
    revision as good or bad without checking it out first.

    If you supply a command, it will be used for automatic bisection.
    Its exit status will be used to mark revisions as good or bad:
    status 0 means good, 125 means to skip the revision, 127
    (command not found) will abort the bisection, and any other
    non-zero exit status means the revision is bad.

    .. container:: verbose

      Some examples:

        try:
            while changesets:
                # update state
                state['current'] = [node]
                hbisect.save_state(repo, state)
                status = util.system(command, out=ui.fout)
                if status == 125:
                    transition = "skip"
                elif status == 0:
                    transition = "good"
                # status < 0 means process was killed

    revision as good or bad without checking it out first.

    If you supply a command, it will be used for automatic bisection.
    The environment variable HG_NODE will contain the ID of the
    changeset being tested. The exit status of the command will be
    used to mark revisions as good or bad: status 0 means good, 125
    means to skip the revision, 127 (command not found) will abort the
    bisection, and any other non-zero exit status means the revision
    is bad.
