We create a new fuction in dynamic utils for ssh functionality which other files can use. Logging router and network which we use in every 5th iteration for the resources will help for debugging. Change-Id: Iddc4a1a410670b902f0bc1154a1d28a58b00dcda |

Browbeat Rally Plugin: dynamic-workloads ======================================
Introduction:
Dynamic workloads are workloads that aim to simulate a realistic Openstack customer environment, by introducing elements of randomness into the simulation. A list of the different workloads that are part of this Browbeat Rally Plugin is mentioned below.
VM:
- create_delete_servers: Create 'N' VMs(without floating IP), and delete 'M' randomly chosen VMs from this list of VMs.
- migrate_servers: Create 'N' VMs(with floating IP), and migrate 'M' randomly chosen VMs from this list of VMs across computes, before resizing them.
- swap_floating_ips_between_servers: Swap floating IPs between 2 servers. Ping until failure after dissociating floating IPs, before swapping them. Ping until success after swapping floating IPs between 2 servers.
Octavia:
- create_loadbalancers: Create 'N' loadbalancers with specified 'M' pools and 'K' clients per Loadbalancer.
- delete_loadbalancers: Deletes 'M' loadbalancers randomly from 'N' loadbalancers
- delete_members_random_lb: Deletes 'M' members from a random loadbalancer
Trunk(pod simulation):
- pod_fip_simulation: Simulate pods with floating ips using subports on trunks and VMs. Create 'N' trunks and VMs and 'M' subports per trunk/VM. Ping a random subport of each trunk/VM from a jumphost.
- add_subports_to_random_trunks: Add 'M' subports to 'N' randomly chosen trunks. This is to simulate pods being added to an existing VM.
- delete_subports_from_random_trunks: Delete 'M' subports from 'N' randomly chosen trunks. This is is to simulate pods being destroyed.
- swap_floating_ips_between_random_subports: Swap floating IPs between 2 randomly chosen subports from 2 trunks.
Provider network:
- provider_netcreate_nova_boot_ping: Creates a provider Network and Boots VM and ping
- provider_net_nova_boot_ping: Boots a VM and ping on random existing provider network
- provider_net_nova_delete: Delete all VM's and provider network
Shift on Stack:
- shift_on_stack: Runs specified kube-burner workload through e2e-benchmarking. e2e-benchmarking is a repository that contains scripts to stress Openshift clusters. This workload uses e2e-benchmarking to test Openshift on Openstack.
How to run the workloads?
- cd to the base directory(browbeat).
- Change enabled to true under the dynamic-workloads and dynamic-workload section of browbeat-config.yaml.
- Make changes to parameters under the dynamic-workloads section of browbeat-config.yaml.
- Run
./browbeat.py rally
