Update the benchmarks-ci-*.yml files and add supporting file for WIP scheduling flow. (aspnet#2099)

* Fix missing timeoutInMinutes by updating the liquid template to use a default filter for setting it instead of an if else check.
* Update the scenario yaml files in benchmarks_ci.json to be the actual names and not just the temporary placeholders.
