Move initial list creation to create-prefix-shard.
This move the initial list population of produce-transactions
to create-prefix-shard rpc with 3 hardcoded prefixes(prefix-1,prefix-2,prefix-3)
so that csit suites can populate the id-int list just once when the shard is created
and produce-transactions can now run parallely on multiple entries from
multiple nodes.
