Story (Required)

Currently tekton-pipelines-controller leader election is configured in the configmap `config-leader-election` which is also the default value for knative controllers. Any configuration done here is getting read by all controllers like pac, triggers, resolver etc.

Approach (Required)

We should change the name of configmap to something like tekton-pipelines-controller-config-leader-election and pass to deployment using the env so that it is configured only for controller.

Acceptance Criteria (Mandatory)

Other controllers are not affected by change in leader election of tekton-pipelines-controller

• Acceptance criteria are met
