manifestcache: add some test involving shares

Some issue around shares have been reported. I am adding tests to better cover
the share case. The test show that the code behave as expected so far.

Differential Revision: https://phab.mercurial-scm.org/D7602

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

    class delayedlockrepo(repo.__class__):
