Gitlab::Metrics::Instrumentation.instrument_class_hierarchy

Recursively instruments all subclasses of the given root module.

This can be used to for example instrument all ActiveRecord models (as
these all inherit from ActiveRecord::Base).

This method can optionally take a block to pass to `instrument_methods`
and `instrument_instance_methods`.

root - The root module for which to instrument subclasses. The root
       module itself is not instrumented.
