Update SIG Autoscaling in sigs.yaml

This updates the mission statement for SIG Autoscaling to correspond to
the scope of SIG Autoscaling in the charter.

It also ensures that SIG Autoscaling has the right subprojects listed (cluster
autoscaler, vertical pod autoscaler, horizontal-pod-autoscaler, and
scale-client, cluster proportional autoscalers, addon-resizer), moving the
metrics project to SIG instrumentation where it belongs.

 # Autoscaling Special Interest Group
 
-Covers autoscaling of clusters, horizontal and vertical autoscaling of pods, setting initial resources for pods, topics related to monitoring pods and gathering their metrics (e.g. Heapster)
+Covers development and maintenance of componets for automated scaling in Kubernetes.  This includes automated vertical and horizontal pod autoscaling, initial resource estimation, cluster-proportional system component autoscaling, and autoscaling of Kubernetes clusters themselves.
