Review comment:
Something to consider: Rather than adding new API for every ringbuffer
backed type, since the ringbuffers are named, can we just have one API that
retrieves records from a buffer specified by name?
E.g.
public List<LogEntry> getLogEntries(String name)
Then, LogEntry is a generic type capable of accepting any protobuf encoding.
Then, we derive new types from LogEntry such as BalancerDecision. Have a static
method in LogEntry for instantiating the subclasses by reflection based on what
type is communicated by the protobuf.
If _LogEntry_ is too generic a name, consider _RingEntry_. (I'm not the best
at naming, maybe someone else has a better idea...)
It is a lot easier to add or remove specialized classes as these things
evolve than add or remove methods from public/stable admin APIs.
