hsflowd
Allow reporting on both containers and VMs at the same time (e.g. "make LIBVIRT=yes DOCKER=yes").
Improve container lifecycle so that containers are removed promptly after they exit.
Eliminate use of /etc/hsflowd.state file for mapping container/VM to sFlow dsIndex. Replaced with hashing scheme.
Reduce counter-polling overhead by refreshing interface counters only when necessary.
