Summary: Make congestion backoff time configurable
Key: HDFS-17242
URL: https://issues.apache.org/jira/browse/HDFS-17242
Project: Hadoop HDFS
Issue Type: Improvement
Components: hdfs-client
Affects Versions: 3.4.0
Reporter: farmmamba
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.
