Schema event builder allocate 4kb buffer to write 8 byte `EventHeader`

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

If you log `ByteBuffer[]` generated by `SchemaEventBuilder` just before sending, you can see 2 buffers, one of these has `limit==8` and `capacity==4096`. The event header is written to a separate buffer which is not used after this.
```
16:34:21,151 (pool-4-thread-1) ERROR RequestManager:319 java.nio.HeapByteBuffer[pos=0 lim=8 cap=4096]
16:34:21,151 (pool-4-thread-1) ERROR RequestManager:319 java.nio.HeapByteBuffer[pos=0 lim=228 cap=4096]

```

### Expected Behavior

Will be good to use the same buffer for both event header and the event payload.
