This patch refactors the stress-ng workload code
to make it easier to integrate with dynamic workloads.
A parameter has been added for nova_api_version as this is required
in dynamic workloads to use tags for VMs.
The file stress-ng.py has been renamed to stress_ng.py
and stress-ng.yml to stress_ng.yml, in order to adhere to Python
module naming conventions. Without this change, a syntax error occurs
while importing the module. Common code that can be used for dynamic
workloads has been moved to a new file called stress_ng_utils.py.
