mcilwain 4606b1d08e Only inject EPP metric builder in a single place ... This fixes recording of number of attempts and command name on EPP flows, which was broken because a separate metric builder was being injected in two places, EppController and FlowRunner, with the one injected into FlowRunner being discarded rather than having changes applied to the same instance as in EppController. This also adds a test that the metric is created successfully inside a flow. Note that tests already exist for EppController to ensure that the metric is recorded correctly. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=152306596		2017-04-10 13:37:18 -04:00
