> ReplicationEndpoints contain a MetricsSource class that can update a fixed
> set of key replication metrics. It does not, however, allow a developer
> implementing a custom ReplicationEndpoint to create/update custom metrics
> unique to the new endpoint's use case.
> As it turns out, MetricsSource wraps a class, which in turn wraps a class,
> that implements the Hadoop BaseSource interface, which does allow for custom
> metrics. Simply having the two wrappers implement BaseSource as well with
> pass-through methods should be straightforward, and would allow replication
> endpoints to use these generic metric methods.
