ref: Drop ListNewBlobs RPC
The ListNewBlobs()
RPC call has been replaced by the more flexible
alternative ListBlobs()
, which can do the same but across multiple new
refs at once. The last callsite in Rails has been removed in 0bc19a62ac3
(gitaly_client: Remove unused #list_new_blobs
function, 2021-09-15),
so it is not used anywhere anymore.
Remove the RPC call.
