Similar to backstore attributes, it'd be great if lrbd was capable of passing through TPG parameters to targetcli without processing them locally.

IIUC, the current lrbd configuration syntax is a bit of a mess here:

targetcli/LIO backstore attributes are currently in the lrbd tpg[] section, with a backstore_ prefix
- configfs path is target/core/\<backstore>_X/\<name>/attrib/\<attr>
TPG attributes are in the lrbd targets[] section with a tpg_ prefix(!?)
- configfs path is target/iscsi/\<iqn>/tpgt_Y/attrib/\<attr>
targetcli exposes separate TPG "parameters", where should this be located for lrbd config?
- configfs path is target/iscsi/\<iqn>/tpgt_Y/param/\<param>
