Description

Currently，if we enable congestion backoff, we will actually invoke backOffIfNecessary method. and the backoff time is computed using CONGESTION_BACKOFF_MEAN_TIME_IN_MS and CONGESTION_BACK_OFF_MAX_TIME_IN_MS which are hard-code. We should better make them configurable to compute backoff sleep time flexibly.
