Story (Required)

As a cluster-admin trying to change some performance related flags on the tektoncd-pipeline controller I want to be able to do this through the operator configuration (TektonConfig)

The idea is to allow cluster-admins to configure their pipeline controller instance "with ease" so that their instance can handle more objects.

This is the design phase

Background (Required)

Link to support case (https://access.redhat.com/support/cases/#/case/03386276) and workaround issue .

Out of scope

• Possibly other controller's option

Approach (Required)

2 ways:

• Expose some "controller extra flags" field for the pipeline part of TektonConfig
• Expose some "generic extra flags" or "mutation expression" on the main TektonConfig (that could target any payload managed by the controller)

Acceptance Criteria (Mandatory)

I can set performance flags (QPS, …) from the operator without having to patch the TektonInstallerSet
