repository: Remove object pool replication
The ReplicateRepository
RPC optionally supports object pool
replication when the replicate_object_deduplication_network_membership
option is enabled. This option was originally intended to simplify
object pool replication, but has gone unused and is also incompatible
with transactions.
Remove object pool replication support from the ReplicateRepository
RPC to simplify and more easily support transactions.
