    [BEAM-2096] Make DataflowMetrics more resilient

    DataflowMetrics seems to have many hard-coded assumptions about what will be
    returned by the Dataflow service that, which will likely break when users
    use new types of metrics or if the Dataflow service makes minor adjustments
    in our it sends metrics back to the user.
    
    In order for code to continue working in these cases, handle errors by logging
    and skipping.
