----------------------------------------------------------------------

2.1 and 2.2 build on the CASSANDRA-10511 branches. The 3.0 branch doesn't need the 10511 changes
so it's just off 3.0.

> If we downsample an index summary, we overwrite the existing summary, despite downsampling
being inexpensive. However on upsampling (which is expensive) we do not, so that on restart
all of our index summaries are the smallest they have ever been adjusted to.
