Proposal to adopt event based pruner to tektoncd org

[anithapriyanatarajan]

This PR includes the TEP to adopt Event-based-Pruner to the tektoncd org.

The Event-based-Pruner proposes an event triggered mechanism to cleanup completed PipelineRuns and TaskRuns as and when the Runs are completed based on pruner configurations defined in a configMap.

Thank @anithapriyanatarajan for this very interesting proposal. If I understood correctly, this would be a new project in the tektoncd org.

There some additional questions that the TEP should address, in particular who will maintain the project, see the link for more details.

The @tektoncd/governing-board needs to vote on this, however @tektoncd/results-maintainers and @tektoncd/operator-maintainers may want to review as well.

@afrittoli @vdemeester - Thankyou. Captured the required details in the Issue#1209. Please verify and suggest if anything further needs to be added.
