Takashi Kajinami c06a9ff796 Drop explicit dependency on python-subunit
It is no longer directly used by any test code in this repository since
we switched to stestr[1].

It is now installed as a dependency of stestr.

Tap as a Service

Tap-as-a-Service (TaaS) is an extension to the OpenStack network service (Neutron). It provides remote port mirroring capability for tenant virtual networks.

Port mirroring involves sending a copy of packets entering and/or leaving one port to another port, which is usually different from the original destinations of the packets being mirrored.

This service has been primarily designed to help tenants (or the cloud administrator) debug complex virtual networks and gain visibility into their VMs, by monitoring the network traffic associated with them. TaaS honors tenant boundaries and its mirror sessions are capable of spanning across multiple compute and network nodes. It serves as an essential infrastructure component that can be utilized for supplying data to a variety of network analytics and security applications (e.g. IDS).

For installing Tap-as-a-Service with Devstack please read the INSTALL.rst file
