Gian Merlino ea03906fcf Configurable compressRunOnSerialization for Roaring bitmaps. (#3228) 
Defaults to true, which is a change in behavior (this used to be false and unconfigurable).

Björn Zettergren 2462c82c0e New defaults for maxRowsInMemory rowFlushBoundary 
To bring consistency to docs and source this commit changes the default
values for maxRowsInMemory and rowFlushBoundary to 75000 after
discussion in PR https://github.com/druid-io/druid/pull/2457.

The previous default was 500000 and it's lower now on the grounds that
it's better for a default to be somewhat less efficient, and work,
than to reach for the stars and possibly result in
"OutOfMemoryError: java heap space" errors.
