    Report reserved_host_disk_mb in GB not KB
    
    We were reporting reserved_host_disk_mb as GB not KB.
    
    This created this log message:
      Invalid inventory for 'DISK_GB' on resource provider <uuid>.
      The reserved value is greater than or equal to total.
    
    This corrects the reporting of reserved_host_disk_mb to the placement
    API when updating the compute node inventory.
    
    Closes-Bug: #1661243

Title:
  reserved_host_disk_mb reporting incorrectly

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  We're getting the following failure in our gate jobs for nova:

  Failed to update inventory for resource provider 2c2e388f-be21-4461
  -bdcf-e1b20b9c90e2: 400 400 Bad Request

  The server could not comply with the request since it is either
  malformed or otherwise incorrect.

   Unable to update inventory for resource provider 2c2e388f-be21-4461
  -bdcf-e1b20b9c90e2: Invalid inventory for 'DISK_GB' on resource
  provider '2c2e388f-be21-4461-bdcf-e1b20b9c90e2'. The reserved value is
  greater than or equal to total.

  =====================================

  The reserved_host_disk_mb is set to 2048 and the compute host is showing free disk of 57GB.
  The build is done based on head of master of nova, and uses QEMU
