phabricator: add a "phabstatus" show view

We add a "phabstatus" show view (called as "hg show phabstatus") which
renders a dag with underway revisions associated with a differential
revision and displays their status.

The revisions shown is a subset of that shown by "work" view, only
including revisions with known by Phabricator.

Differential Revision: https://phab.mercurial-scm.org/D7506

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
