Story (Required)

Existing Pruner code base https://github.com/openshift-pipelines/tektoncd-pruner has to be updated to incorporate the revised design items (https://docs.google.com/document/d/1FT1kQZFVFmcbhEuMslMdmChBtvF-BB_YMupS-nUmD2Y/edit?tab=t.vddydnsjzth8) 

Background (Required)

_In response to the design review feedback for Pruner, the existing approach to drop custom resource in favor of a configmap at namespace level to manage namespace level pruning configurations along with configmap abstraction to accomodate PAC grouping needs, new design has been published with https://issues.redhat.com/browse/SRVKP-6957_ 

Out of scope

Code changes to address Watching and handling pruning behavior based on namespace level configmap is out of scope of this story.

Approach (Required)

• Introduce a config map processor that loads the revised configmap and updates a local store
• Controller that watches this confignmap and updates the local stores whenever the configmap is updated
• PipelineRun Controller that watches and reconciles the pipelineRuns based on the pruning configuration
• TaskRun Controller that watches and reconciles the pipelineRuns based on the pruning configuration
•  

Dependencies

<Describes what this story depends on. Dependent Stories and EPICs should be linked to the story.>

Acceptance Criteria (Mandatory)

Are the PipelineRuns and TaskRuns pruned succesfully based on the configmap settings?
