Make ActionStats a private-static inner class of MetricsCollector

The google style guide dicates one top-level class per java file:
https://google.github.io/styleguide/javaguide.html#s3.4.1-one-top-level-class.
Since this class isn't used anywhere else, just move it into MetricsCollector
and make it private.
