Provide ability to retrieve coverage information
Previously, there was no way to induce coverage information to be
displayed; it would only print when the system noticed unusual delays
between polling intervals. Now, production of coverage logs can be
forced with "coverage/log" command in ovs-appctl. Coverage counters may
be reset with "coverage/clear".
