dynamic workloads should have selective resource creation depending on the workload enabled

[jaison]

For example when only is enabled, the dynamic workload also creates extra routers and network.
The routers are created due to the following common code for all workloads.
https://github.com/cloud-bulldozer/browbeat/blob/master/rally/rally-plugins/dynamic-workloads/dynamic_workload.py#L86-L87

There are networks created due to rally_context too. These are the subnets with 172.31.xx.xx

We need to have another review of the code to understand how we can selectively create resources so that they dont get created for workloads for which its not required.

I created a patch to fix the router issue.

Changes have been to the same patch to fix the external networks issue as well.

[Sanjay Chari (sanjaychari)]

The patch that fixes this issue(mentioned in the first comment) has been merged.
