Remove hard_rate_limit and rate_limit_delay_max_milliseconds and other options that are accepted but ignored

### Behavior

The options (hard_rate_limit, rate_limit_delay_max_milliseconds) are parsed by db_bench and accepted but ignored by RocksDB. They are noops, which will mislead users into thinking they are useful. The path forward is one of:
* translate them to existing options
* remove support for them (remove all references to them)

They [are listed](https://github.com/facebook/rocksdb/blob/main/include/rocksdb/advanced_options.h#L917) in the "Not supported anymore" section of advanced_options.h. I prefer that RocksDB not have options that are accepted but ignored. Other options in that section are: soft_rate_limit, max_mem_compaction_level, purge_redundant_kvs_while_flush
