Replace top level go mod with project specific dependency model

The Platform Aware Scheduling repository now contains multiple go
dependency files - using a go.mod file in each subproject. This
commit adds the files for the extender and Telemetry Aware
Scheduling directories and removes the older single go.mod at
the top level of the repo.

+## Adding a new extender to Platform Aware Scheduling
+Platform Aware Scheduling is a single repo designed to host multiple hardware enabling Kubernetes Scheduler Extenders. A new scheduler can be added with an issue and pull request.
+
+Each project under the top-level repo has its own go module, dependency model and lifecycle.There is no single top level go.mod for the project. Some development tools and testing workflows may need to be done in the context of the go module they're targeting i.e. by changing into one of the directories that contains a go module.
