Fixed so that logger implements behavior as described by Jeremy:
- Loggers have two buffer limits: threshold and max size
- When the buffer size reaches threshold, send to OLL
- If the Send fails, keep logs in buffer and fill until max
- If buffer reaches max size, drop oldest logs in replace of new ones
Big Changes: Added a wrapper class for the log entry buffer that allows
for thread safe actions.  This allowed me to rework the logging
implementation to make it much more simple and clear
Changed oohlalog.properties to include the option to manage the
threshold
