issue: #36977
with node_label_filter on resource group, user can add label on
querynode with env `MILVUS_COMPONENT_LABEL`, then resource group will
prefer to accept node which match it's node_label_filter.
then querynode's can't be group by labels, and put querynodes with same
label to same resource groups.
