Misleading client.batch-wait flag

[ukrainian-im]

As currently implemented, the flag name should probably be "client.line-wait",
as it controls max duration between stream.append.entry(), and not duration between send.batch().

Not clear what original intent was.

Either flag name/description should be changed, or implementation changed from

	for {
		maxWait.Reset(c.cfg.BatchWait)
		select {
                .
                .
                .
		}
	}

to

	maxWait.Reset(c.cfg.BatchWait)
	for {
		select {
                .
                .
                .
		case <-maxWait.C:
                      .
                      .
                     .
                      maxWait.Reset(c.cfg.BatchWait)
		}		
	}
