customized_metric_specification metrics is missing

[tetienne]

Description

While trying to add a custom metric for one of my project, I was not able to find how to specify... well the metrics.

It looks like this field is not handle. Here the definition of customized_metric_specification, and here where this module build it. If I’m not wrong the metrics attribute is missing.

Expected behavior

Be able to create an autoscalling policy based on a custom metrics.

Actual behavior

metrics is not handle.
