add base scripts to test GKE elasticity (#176)

we will do more work with this to integrate the flux operator
in too.

+## Google GKE Autoscaling
+
+> Using Google Cloud APIs to autoscale + Flux Operator autoscaling
+
+These classes and assets are intended to help with autoscaling experiments.
+
+Tests of elasticity, for GKE and the Flux Operator, will help us move us a tiny step toward the goal of 
+trying to control both the GKE cluster scaling and MiniCluster scaling from the same
+script. This way, theoretically, some other algorithm (that is smarter than my manual calls) can do it too.
+See the [elasticity page](https://flux-framework.org/flux-operator/tutorials/elasticity.html) for early work.
+
+To start, however, we just want to look at some basic elasticity or scaling for Kubernetes by itself.
+All experiments use the shared class in [fluxcluster.py](fluxcluster.py), and an example experiment
+is [test-scale.py](test-scale.py).
+
+
+### Dependencies
+
+We will need the google cloud APIs
+
+```bash
+$ python -m venv env
+$ source env/bin/activate
+# https://github.com/googleapis/python-container
+$ pip install google-cloud-container
+$ pip install kubernetes
+```
+
+### Experiments
+
+The scripts are provided here to do experiments, and you can see results [here](https://github.com/converged-computing/operator-experiments/tree/main/google/autoscale/run1).
