Fix bug with Gamma Server Runner not having GCP Logs link (#26)

This fixes a bug with all the `GammaServerRunner` subclass not calling
the super class `KubernetesBaseRunner`'s `run()` method properly, which
causes the variable `self.time_start_requested` not being set and hence
there is never `RunHistory` logged for the gamma server runner.
