This patch adds the support of read and write separate bandwidth rate limits control with the configuration file. Below is the example (in MiB) for the configuration section: [QoS] Limit_Read_BPS Malloc0 100 Limit_Write_BPS Nvme0n1 200 Change-Id: I0221516ce70c3fbb07b9e80c1c814ed5ba271c88 Signed-off-by: GangCao <gang.cao@intel.com> Reviewed-on: https://review.gerrithub.io/c/416672 Chandler-Test-Pool: SPDK Automated Test System <sys_sgsw@intel.com> Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Shuhei Matsumoto <shuhei.matsumoto.xt@hitachi.com> Reviewed-by: Ben Walker <benjamin.walker@intel.com>
