Define a FlushPolicy where a max number of bytes will be flushed to GCS per flush.
If there are not enough bytes to trigger a flush, they will be held in memory until there
are enough bytes, or an explicit flush is performed by closing the channel. If more bytes are
provided than the configured maxFlushSize, multiple flushes will be performed.
Instances of this class are immutable and thread safe.
