Cassandra resolves pluggable extensions by class name from configuration, schema, and tooling
inputs. These names were loaded with an initializing Class.forName(name) and type-checked only
afterward, so the named class ran its static initializer before its type was confirmed. After this
change such classes will be loaded without initialization, verified against the expected interface or
base class, and initialized only through normal use after validation.
A shared FBUtilities.classForNameWithoutInitialization helper and typed
instanceOrConstruct/construct overloads apply this to the configurable extension points loaded by
class name: the authentication, authorization, role-management, network and
internode-authenticator backends, the partitioner, audit logger, configuration loader, seed provider,
snitch, abstract types, secondary and custom indexes, compaction strategy, compressor, replication
strategy, SASI analyzers, key and cache providers, query handler, storage and stream hooks, tracing,
the JMX authorization proxy, MBeans, the monotonic clock, nodetool Sjk, triggers, the
sstableloader and stress class options, and diagnostic event classes (loaded without initialization
and checked against DiagnosticEvent, preserving the InvalidClassException contract and the existing
package restriction).
Regression tests confirm that an invalid-type load is rejected without initializing the target
class, and that valid implementations still resolve.
Hadoop client integration and hard-coded JDK and internal class probes are left unchanged.

If fullquerylog is enabled and a prepared query executed with null value
binded, then fqltool dump is running into NPE. Checking value for null before
wrapping it.

commented out by mistake in a previous patch;
Fix breaking change with cache_load_timeout; cache_load_timeout_seconds <=0 and cache_load_timeout=0 are equivalent
and they both mean disabled;
Deprecate public method setRate(final double throughputMbPerSec) in Compaction Manager in favor of
setRateInBytes(final double throughputBytesPerSec);
Revert breaking change removal of StressCQLSSTableWriter.Builder.withBufferSizeInMB(int size). Deprecate it in favor
of StressCQLSSTableWriter.Builder.withBufferSizeInMiB(int size);
Fix precision issues, add new -m flag (for nodetool/setstreamthroughput, nodetool/setinterdcstreamthroughput,
nodetool/getstreamthroughput and nodetoo/getinterdcstreamthroughput), add new -d flags (nodetool/getstreamthroughput,
nodetool/getinterdcstreamthroughput, nodetool/getcompactionthroughput);
Fix a bug with precision in nodetool/compactionstats;
Deprecate StorageService methods and add new ones for stream_throughput_outbound, inter_dc_stream_throughput_outbound,
compaction_throughput_outbound in the JMX MBean `org.apache.cassandra.db:type=StorageService`;
Removed getEntireSSTableStreamThroughputMebibytesPerSec in favor of new getEntireSSTableStreamThroughputMebibytesPerSecAsDouble
in the JMX MBean `org.apache.cassandra.db:type=StorageService`;
Removed getEntireSSTableInterDCStreamThroughputMebibytesPerSec in favor of getEntireSSTableInterDCStreamThroughputMebibytesPerSecAsDouble
in the JMX MBean `org.apache.cassandra.db:type=StorageService`
