Describe the issue

I have two bigtable clusters in the same project
The get_cpu_load() function returns the metrics for the first one it detects in the iteration. In my case it was not the one requested to autoscale.
The autoscaler resizes the requested cluster, based on the metrics of the wrong cluster.
