<description>
Maximum bandwidth used for regular image transfers (instead of
bootstrapping the standby namenode), in bytes per second.
This can help keep normal namenode operations responsive during
checkpointing.
A default value of 0 indicates that throttling is disabled.
A default value is 50mb per second.
The maximum bandwidth used for bootstrapping standby namenode is
configured with dfs.image.transfer-bootstrap-standby.bandwidthPerSec.
Support multiple size unit suffix(case insensitive), as described
