---------------------------------------
Hi [~djoshi], making the initial size and the growth factor tunable is
especially useful in the case when getting many deletes for a single partition.
With a larger initial size and growth factor, it helps to reduce the cost of
frequent array resizing/allocation underneath.

> Cassandra allocates a backing array with a fixed size of one when creating a
> new RangeTombstoneList object. The resize factor is fixed to 1.5.
> The initial size and resize factor could be made tunable so it could reduce
> cost in some cases.
