Update BulkProcessor size in the example

ismael-hasan · web-flow · commit 7906db83d55e · 2016-11-18T16:52:46.000+01:00
By default, it is recommended to start bulk with a size of 10-15MB, and increase it gradually to get the right size for the environment. The example shows originally 1GB, which can lead to some users to just copy-paste the code snippet and start with excessively big sizes. Backport of elastic#21664 in master branch.
