cloudstack: fix tests to avoid accessing /var/lib/NetworkManager

on centos/fedora/rhel, /var/lib/NetworkManager has mode 700, causing
the cloudstack unit tests to fail when run as a non-root user.  This
mocks out get_latest_lease so that we no longer try to read dhcp lease
information during the unit tests.
