Bug description:
  The current implementation of bandwidth limiting rules only supports egress bandwidth
  limiting.

  Use cases
  =========
  There are cases where ingress bandwidth limiting is more important than
  egress limiting, for example when the workload of the cloud is mostly a consumer of data (crawlers, datamining, etc), and administrators need to ensure other workloads won't be affected.

  Other example are CSPs which need to plan & allocate the bandwidth
  provided to customers, or provide different levels of network service.

  API/Model impact
  ===============
  The BandwidthLimiting rules will be added a direction field (egress/ingress), which by default will be egress to match the current behaviour and, therefore
  be backward compatible.

  Combining egress/ingress would be achieved by including an egress
  bandwidth limit and an ingress bandwidth limit.

  Additional information
  ======================
  The CLI and SDK modifications are addressed in https://bugs.launchpad.net/python-openstackclient/+bug/1614121
