Nightly performance tests

[lbernick]

Subtask of #5452.

As part of tektoncd/community#602 and our goals for Pipelines V1 we'd like to have some way to regularly measure Pipelines performance. I think the easiest way to start out would be to create a periodic prow job (like our existing upgrade tests) that run some version of #4378. It doesn't have to be perfect-- we can adapt these tests as time goes on, and just having some form of regular performance measurement will be a great start.
