DO NOT MERGE Add metric log for anomaly.

This cl creates metric log when anomaly surfaces in battery page or
anomaly dialog.

Each anomaly action contains two fields:
1. FIELD_CONTEXT(int): determine which fragment start this action.
2. FIELD_ANOMALY_ACTION_TYPE(int): determine action type for this
anomaly.
