geo-rep: Make changelog-batch-size configurable
Changelog batch size is set to 727040 bytes which
is the size of all the changelogs in a single batch.
It's based on few tests which approximately processes
5K entries. But it might vary on different machines.
Making it configurable gives more control on the
frequency of stime updates. This patch does the same.
