commit: add --force-close-branch flag to close a non-head changeset

While closing branch from a changeset which is not a branch head
current implementation abort this action in every case but, there
can be the situations where the changeset is not a local head but
could be a remote head. This patch adds the functionality to bypass
the "abort: can only close branch heads" by introducing
--force-close-branch flag.

Test case changes demonstrate the new functionality added.

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