iscsi-target: Add tpg_enabled_sendtargets for disabled discovery
This patch adds a new tpg_enabled_sendtargets configfs attribute to allow in-band sendtargets discovery information to include target-portal-groups (TPGs) in !TPG_STATE_ACTIVE state. This functionality is useful for clustered iSCSI targets, where TPGTs handled on remote cluster nodes should be advertised in the SendTargets response. By default, this new attribute retains the default behaviour of existing code which to ignore portal-groups in !TPG_STATE_ACTIVE state.
