This patch adds a new configuration file, cassandra_latest.yaml, which changes
some of the settings to use new features we usually recommend to users,
including:
- Big Trie-Indexed SSTables
- Trie memtables
- Unified Compaction Strategy
- Storage Attached Index
- Off-heap objects memtables
- Direct-write commit log
- No storage compatibility
These changes are applied in new test targets for unit, in-jvm and python dtests that are
run pre-commit. When changes are made to the new config file, python dtest will use it
directly, but unit and in-jvm dtests require updates, respectively, to latest_diff.yaml
and InstanceConfig.java.

This patch removes deprecated chunk_length_kb and sstable_compression in favor of
chunk_length_in_kb and class parameters.
The only deprecated compression parameter left, crc_check_chance (which is configurable outside
of compression parameters as a standalone table parameter) is meant to be treated separately.

As we were implementing the snitch itself, we noticed that the constructors
for cloud-based snitches are unnecessarilly complicated and
we took the opportunity to make them simpler.

The approach is documented in the included UnifiedCompactionStrategy.md.
Also included:
- Generalize prettyPrint to prettyPrintBinary (with 2^10 multiplier,
e.g. MiB) and prettyPrintDecimal (with 1000 multiplier, e.g. ms)
that cover the full range of double, and add a parseHumanReadable
method that can read both.
- CASSANDRA-18123: Fix invalid reuse of metadata collector during flushing
- Fix invalid token range splitting with non-unit weights
- Add flushSizeOnDisk metric
- Add ability to change compaction default in YAML

The patch also refactors existing cloud snitches to get rid of the duplicate code,
this is the logical follow-up of CASSANDRA-16555 where AbstractCloudMetadataServiceConnector was introduced.
