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.
patch by Stefan Miklosovic; reviewed by German Eichberger and Jacek Lewandowski for CASSANDRA-18646
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.

Allows to attach the native masking functions and UDFs to the definitions of
table columns in the schema, as defined by CEP-20.
The functions masking a column can be specified on CREATE TABLE queries, right
at the end of the column definition. The mask of a column can also be changed
or dropped with an ALTER TABLE query. Once a column is masked, SELECT queries
will always return the masked value of the column. That masking is done on the
coordinator, at the end of the query execution. Thus, masking won't affect any
filters or ordering, which would be based on the clear values of the masked
columns. Column masks are stored on the table system_schema.column_masks.
A new UNMASK permission allows to see the clear data of columns with an
attached mask. Also, a new SELECT_MASKED permission allows to run SELECT
queries restricting the clear values of masked columns. Superusers have both
permissions by default, whereas regular users don't have them.
Dynamic data masking can be enabled/disabled with the config property
dynamic_data_masking_enabled in cassandra.yaml. It is disabled by default.
This is the combination of multiple tickets:
* Add masking functions to column metadata (CASSANDRA-18068)
* Add UNMASK permission (CASSANDRA-18069)
* Add SELECT_MASKED permission (CASSANDRA-18070)
* Add support for using UDFs as masking functions (CASSANDRA-18071)
* Add feature flag for dynamic data masking (CASSANDRA-18316)
