Add 'logical_decoding_mode' GUC. This enables streaming or serializing changes immediately in logical decoding. This parameter is intended to be used to test logical decoding and replication of large transactions for which otherwise we need to generate the changes till logical_decoding_work_mem is reached.
This helps in reducing the timing of existing tests related to logical replication of in-progress transactions and will help in writing tests for for the upcoming feature for parallelly applying large in-progress transactions.
