Configure Thread, QPS and Burst with env vars

[valAndre07]

Hello everyone 👋

I wanted to increase the performance of tekton controller, like indicated in the documentation.
As I use helm charts from cdfoundation to deploy tekton controller, it could be easier to add the possibility to configure threads-per-controller, kube-api-qps and kube-api-burst by environment variables rather than by args.

Searching deeper in the source code, I think I could use :

• KUBE_API_BURST
• KUBE_API_QPS

environment variables for kube-api-qps and kube-api-burst. Am I wrong ?
Also, is there an env var for configuring threads-per-controller ?

Thanks in advance ☀️
