Add MetricsLogger to connector- and pipeline-calls.

  • By default, all pipelines (env-to-module, module-to-env, and learner) now track individual pieces' times.
  • By default, env-to-module AND learner pipelines now track sum-of-lengths of incoming and outgoing episodes.

Why are these changes needed?
