Scenario "boot-runcommand-delete" doesn't properly clean resources after completion

[Evgeny Sboychakov]

After successful launching and then stopping the Virtual Machine the "boot-runcommand-delete" scenario does not delete the network created.

The following error could be found in the log:

2015-01-26 12:03:12.201 29512 INFO rally.benchmark.context.network [-] Task d1b3152d-1dc5-4e1e-b209-aa7c8ac78dca | Starting: Exit context: `network`
2015-01-26 12:03:20.717 29512 ERROR rally.benchmark.context.network [-] Failed to delete network for tenant 8d89b6e00bbd4d089e503995decd3ff3
 reason: Unable to complete operation on subnet c5d4d8d6-c812-42fe-a8fa-d3f18831a180. One or more ports have an IP allocation from this subnet.

This network could be deleted manually via Horizon dashboard -> Networks tab. However to do that all ports associated wth the network should be deleted first.

Environment:
existing Fuel environment, Neutron GRE network

The reason is that rally have no code to remove network's ports.

    Neutron: remove ports before removing network

    Fixes rally being unable to remove network because there are still
    ports allocated under it.
