Integrated Locust load testing

[RachalCassity]

Note: Delete the description statements, complete each step. None are optional, but can be justified as to why they cannot be completed as written. Provide known gaps to testing that may raise the risk of merging to production.

Summary

Locust will be used for automated load testing. A Locust script is mounted to the Locust master deployment and worker deployment and deployed to EKS. The Locust command --master -f /locustfile.py is used to run Locust in master mode while specifying the location of the locustfile in the ConfigMap. The worker deployment may not be needed in the future. Load test can be initiated in the Locust UI.

Potential Modifications if this fails:

1. Add host to class APIUser method. We do not want to use staging-api.va.gov.
   class APIUser(HttpUser): abstract = True task_set = VetsApiClient min_wait = 0 max_wait = 1000 host = 'https://staging-api.va.gov' # Will need domain for VetsNext Cluster
