Description

This mainly concerns cassandra yaml settings:

• column_index_size, which should also be renamed to row_index_granularity
• column_index_cache_size
• index_summary_capacity
• index_summary_resize_interval

and possibly

• key_cache_size, key_cache_keys_to_save, key_cache_save_period, key_cache_migrate_during_compaction
• sstable_preemptive_open_interval

Existing settings should be deprecated but still picked up if defined.

At this point we will not consider table-level options that make better sense as format parameters (min/max_index_interval, bloom_filter_fp_chance, crc_check_chance and possibly compression), because we do not yet support per-table format selection/configuration.
