We had some downstream scaling/performance testing with browbeat/rally, and after the neutron scenarios are executed, we see ODL resources not being cleaned up, including TEP.
Steps to recreate:
1. Bring up devstack (stable/newton) and ODL (master... also broken in stable/carbon).
2. Show TEPs

Tunnel Monitoring Interval (for VXLAN tunnels): 1000

3. Create network
neutron subnet-create vx-net 10.100.5.0/24 --name vx-subnet
4. Create subnet
neutron subnet-delete vx-net
3. Display TEPs

Notice there is a new, 3rd TEP from subnet creation.
4. Delete subnet
neutron subnet-delete vx-net
5. Show TEP, 3rd TEP is still there!
