The implementation of this CEP adds the ability to plug-in custom compressors providers
which might delegate the de/compression to a specialized hardware. An operator does not
need to change any schema definition, the mere implementation of a compressor provider
put on a class path and its related configuration in cassandra.yaml will transparently
start to use appropriate compressor, e.g. backed by a specialized hardware.

Previously users would either have to read the data and check the length
themselves or enable UDF and register UDFs to check the length of
columns. This patch adds a subset of the SQL99 (binary) string
functions: "octet_length" defined on all types and "length" defined on
UTF8 strings.

Deprecate IEndpointSnitch entirely, to be replaced with new interfaces:
* Locator for endpoint -> location mapping
* InitialLocationProvider to supply the DC & rack for registration
* NodeProximity for sorting endpoints and replicas at query time
For migration/upgrade/deprecation, nodes can still be configured with
an IEndpointSnitch implementation via endpoint_snitch in config, but
we hide this with a facade and only present the new interfaces.

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.

Adds 'authenticationMode' and 'metadata' fields to AuthenticatedUser to add context
about how the user was authenticated and updates system_views.clients,
nodetool clientstats (behind --verbose flag) to include this information.
Also adds new metrics to ClientMetrics to help operators identify which
authentication modes are being used.
