Automation of creation of required k8s resources for performance testing

[trepel]

Summary

A way to create a various k8s resources for performance test is required. For a basic load test we need just 1 GW, 1 HTTPRoute, and 1 instance of each Kuadrant policy type but this needs to be configurable so that creating X of each is supported.

Testsuite as is cannot be used since it does not support skipping cleanup.

Potential ways to go (random order):

• simple bash script with yaml templates for various resources using yq
• something like above but written in python
• implementing skip_cleanup feature in testsuite (not preferred imo)
• ripping the required bits & pieces out of testsuite and creating a new repository for them
