Currently not, but not impossible to add, AFAICT.
We can possibly do it in a similar way we use for the non-rrd status kv.
I.e., if the data has zero length we remove the entry from the hashtable,
in the rrd case we could additionally remove the respective DB in
"update_rrd_data" in that case.

But for now not too important, just low priority wishlist.
