InHBASE-14906 we use "hbase.hregion.memstore.flush.size/column_family_number" as the default threshold for memstore flush instead of the fixed value through "hbase.hregion.percolumnfamilyflush.size.lower.bound" property, which makes the default threshold more flexible to various use case.

After this change setting "hbase.hregion.percolumnfamilyflush.size.lower.bound" in hbase-site.xml won't take effect anymore, but expert users could still set this property in table descriptor to override the default value just as before ...
