This patch removes legacy config support in iscsi subsystem. All options through the legacy config are already reflected in JSON. Following RPCs are corresponding to removed legacy config sections: Initiator groups - iscsi_create_initiator_group and iscsi_initiator_group_* Subsystem options - iscsi_set_options Portal groups - iscsi_create_portal_group Target node - iscsi_create_target_node and iscsi_target_node_* Signed-off-by: Tomasz Zawadzki <tomasz.zawadzki@intel.com> Change-Id: I11326a84d4d580b19db422b8522198eea5a5be0d Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/4747 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Community-CI: Broadcom CI Reviewed-by: Ben Walker <benjamin.walker@intel.com> Reviewed-by: Jim Harris <james.r.harris@intel.com>
