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.

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.

Summary of the changes:
Format, reader and writer
---------------------------
There are a lot of refactorings around sstable related classes aiming to extract the most generic functionality to the top-level entities and push down implementation-specific stuff to the actual implementation. In Particular, the top-level, implementation agnostic classes/interfaces are SSTableFormat interface, SSTable, SSTableReader, SSTableWriter, IVerifier, and IScrubber. The rest of the codebase has been reviewed for explicit usages of big table format-specific usages of sstable classes and refactored. SSTable, SSTableReader, and SSTableWriter have their builders. Builders make a hierarchy that follows the same inheritance structure as readers and writers.
There are also partial implementations that add support for some features and may or may not be used by the custom implementations. They include:
- AbstractSSTableFormat - adds an implementation of some initialization methods - in practice, all of the format implementations should extend this class
- SSTableReaderWithFilter - add support for Bloom filter to the reader
- SortedTableWriter - generic implementation for a writer which writes partitions in the default order to the data file, supports Bloom filter and some index of partitions
- IndexSummarySupport - interface implemented by the readers using index summaries
- KeyCacheSupport - interface implemented by the readers using row key cache
Descriptor
---------------------------
Refactored the Descriptor class so that:
- All paths are created from the base directory File rather than from a String
- All the methods named *filename* producing full paths were made private; their current implementations are returning file names rather than paths (the naming was inconsistent)
- The usages of the `filenameFor` method were refactored to use the `fileFor` method
- The usages of the `fromFilename` method were refactored to use a `fromFileWithComponent(..., false).left` expression
In essence, the Descriptor class is no longer working on String-based paths.
Index summaries
---------------------------
Removed the index summary from the generic SSTableReader class and created an interface IndexSummarySupport to be implemented by the readers that need it. Methods in related classes that refer back to the reader were refactored to support just readers of the SSTableReader & IndexSummarySupport type. Therefore, we will no longer need to assume that the generic SSTableReader has anything to do with an index summary.
A new IndexSummaryComponent class encloses data fields from the index summary file (note that aside from the index summary itself, the file includes the first and last partition of the sstable). The class has been extracted to deal with those fields and have that logic in a single place.
Filter
---------------------------
Refactored IFilter and its serialization - in particular, added the `serialize` method to the IFilter interface and moved loading/saving logic to a separate utility class FilterComponent.
Extracted the SSTableReaderWithFilter abstract reader extending the generic SSTableReader with filter support.
Extracted bloom filter metrics into separate entities allowing to plug them in if the implementation uses a filter.
Cache
---------------------------
Refactored CacheService to support different key-cache values. CacheService now supports arbitrary IRowIndexEntry implementation as a key-cache value. A new version of the auto-saving cache was created ("g") because some information about the type of serialized row index entry needs to be known before it is deserialized (or skipped). Therefore, the SSTableFormat type ordinal number is stored, which is sufficient because the IRowIndexEntry serializer is specific to the sstable format type.
Similarly to the IndexSummarySupport, a new KeyCacheSupport interface has to be implemented to mark the reader as supporting key-cache. It contains the default implementation of several methods the rest of the system relies on when the key-cache is supported.
Other changes
---------------------------
- Fixed disabling chunk cache - enable(boolean) method in ChunkCache does not make any sense - it makes a false impression it can disable chunk cache once enabled, while in fact, it only clears it. Added setFileCacheEnabled to DatabaseDescriptor
- Made WrappingUnfilteredRowIterator an interface
- DataInputStreamPlus extends InputStream - this makes it possible for input stream-based inheritors of DataInputPlus to extend DataInputStreamPlus. It simplifies coding because sometimes we want to get DataInputPlus implementation extending InputStream as an argument.
- Table and keyspace metrics were made pluggable - in particular, added the ability for a certain format to register gauges that are specific only to that format and make no sense for others
- Implemented mmapped region extension for compressed data
- Refactored FileHandle so that it is no longer closable
- Implemented WrappingRebufferer
- Introduced the SSTable.Owner interface to make SSTable implementation not reference higher-level entities directly. SSTable accepts passing null as the owner when there is no owner (like sometimes in offline tools) or passing a mock when needed in tests.

This reverts the changes made to the native protocol V5 wire format in
CASSANDRA-13304 and subsequent follow up JIRAs (CASSANDRA-15556 &
CASSANDRA-14716). The framing format has been re-implemented based on the
internode messaging format developed in CASSANDRA-15066.
OPTIONS and STARTUP messages are unframed (i.e. identical to the V4 format).
After sending its response to a STARTUP message, the server modifies the
pipeline and all further messages are sent (and should be expected by the
client to be received) in the format determined by the protocol version of
the STARTUP message.
