Namespace_veth: Add funtionality for network namespace, veth ports

Adds functionality for network namespaces and veth/peer ports
to connect the namespaces. The namespaces are tracked outside
of default Linux namespaces to prevent possible disruption of
work outside of VSPerf where a user may create a namespace and
the cleanup code deletes it. The cleanup code only removes
namespaces and veth ports created inside the testcase.
