Running create_and_list_routers task fails: TypeError: string indices must be integers

[Itzik Brown]

Test fails when running rally -d -v task start create_and_list_routers.yaml
with the YAML:
---
  NeutronNetworks.create_and_list_routers:
    -
      args:
        network_create_args: {}
        subnet_create_args: {}
        subnet_cidr_start: "1.1.0.0/30"
        subnets_per_network: 1
        router_create_args: {}
      runner:
        type: "constant"
        times: 1
        concurrency: 1
      context:
        network: {}
        users:
          tenants: 1
          users_per_tenant: 1
        quotas:
          neutron:
            network: -1
            subnet: -1
            router: -1

Version
======
rally 0.1.2~dev328
RHEL7.2
Openstack Kilo

Seems like the failure comes from:

rally/plugins/openstack/scenarios/neutron/utils.py", line 369, in _create_network_structure
self._add_interface_router(subnet["subnet"],
ERROR rally.task.runner TypeError: string indices must be integers

Scenario NeutronNetworks.create_and_list_routers does not work correctly with `network' context.

However it can be run without `network' context as workaround.

    Make Neutron router scenarios work with network context

    Usage of NeutronNetworks.create_and_*_routers without network context
    is deprecated (ref. https://goo.gl/peijFT), however these scenario can
    not be run with network context due to a bug.

    This patch fixes the bug and also enables the network context in gates
    for all Neutron scenarios that should be using it.
