I have finished the review and materialized that to separate PR to have an
idea. Might be picked to the main branch or just finished ....

> Currently we keep components as a Set in memory and iterate over them without
> a fixed order to write to TOC.txt, so TOC.txt can be different for different
> SSTables, it is a bit annoying to see in tickets like CASSANDRA-20485. To
> make the logic more deterministic we can sort the list in lexicographic order
> in the store logic
