GEODE-9285: Implement accurate sizeable for RedisSet (#6531)
- Extend ObjectOpenCustomHashSet to allow direct access to the current
capacity of the backing array
- Calculate the overhead associated with each member added based on its
length
- Calculate the overhead associated with resizing the backing set in
RedisSet
- Update tests to reflect new behaviour
- Add tests to allow derivation of member overhead and backing array
overhead formulae

> Key: GEODE-9285
> URL: https://issues.apache.org/jira/browse/GEODE-9285
> Project: Geode
> Issue Type: Improvement
> Components: redis
> Affects Versions: 1.15.0
> Reporter: Hale Bales
> Assignee: Donal Evans
> Priority: Major
> Labels: pull-request-available, redis
> Fix For: 1.15.0

>
> RedisSet currently uses constants to help keep track of the size of bytes in
> use by that RedisSet. The way that the size increases when members are added
> is not constant, and is affected by resizing. It is possible to get the
> measurement to be exactly accurate, by dynamically calculating the overhead
> based on the current capacity and how many entries there are. In order to
> test this with mocks, the delta will need to be set to null explicitly after
> it is applied.
