#
# Builds out a default storage node
#   a storage node is a device that contains
#   a storage endpoint for account, container, and object
#   on the same mount point
#
# === Parameters:
#
# [*mnt_base_dir*]
#   (optional) The directory where the flat files that store the file system
#   to be loop back mounted are actually mounted at.
#   Defaults to '/srv/node', base directory where disks are mounted to
#
# [*zone*]
#   (required) Zone is the number of the zone this device is in.
#   The zone parameter must be an integer.
#
# [*weight*]
#   (optional) Weight is a float weight that determines how many partitions are
#   put on the device relative to the rest of the devices in the cluster (a good
#   starting point is 100.0xTB on the drive).
#   Add each device that will be initially in the cluster.
#   Defaults to 1.
#
# [*owner*]
#   (optional) Owner (uid) of rsync server.
#   Defaults to 'swift'.
#
# [*group*]
#   (optional) Group (gid) of rsync server.
#   Defaults to 'swift'.
#
# [*max_connections*]
#   (optional) maximum number of simultaneous connections allowed.
#   Defaults to 25.
#
# [*storage_local_net_ip*]
#   (optional) The IP address of the storage server.
#   Defaults to '127.0.0.1'.
#
#  [*policy_index*]
#    (optional) storage policy index
#    Defaults to undef
