Avoid the pattern where a Random object is allocated, used once or twice, and
then left for GC. This pattern triggers warnings from some static analysis tools
because this pattern leads to poor effective randomness. In a few cases we were
legitimately suffering from this issue; in others a change is still good to
reduce noise in analysis results.
Use ThreadLocalRandom where there is no requirement to set the seed to gain
good reuse.
Where useful relax use of SecureRandom to simply Random or ThreadLocalRandom,
which are unlikely to block if the system entropy pool is low, if we don't need
crypographically strong randomness for the use case. The exception to this is
normalization of use of Bytes#random to fill byte arrays with randomness.
Because Bytes#random may be used to generate key material it must be backed by
SecureRandom.

For the `TraceUtil` methods that accept `Callable` and `Runnable` types, make them generic over a
child of `Throwable`. This allows us to consolidate the two method signatures into a single more

Follows the guidance outlined in https://github.com/open-telemetry/opentelemetry-specification/blob/3e380e2/specification/trace/semantic_conventions/database.dm
* all table data operations are assumed to be of type CLIENT
* populate `db.name` and `db.operation` attributes
* name table data operation spans as `db.operation` `db.name`:`db.hbase.table`
note: this implementation deviates from the recommended `db.name`.`db.sql.table` and instead
uses HBase's native String representation of namespace:tablename.

We get and retain Compressor instances in HFileBlockDefaultEncodingContext,
and could in theory call Compressor#reinit when setting up the context,
to update compression parameters like level and buffer size, but we do
not plumb through the CompoundConfiguration from the Store into the
encoding context. As a consequence we can only update codec parameters
globally in system site conf files.
Fine grained configurability is important for algorithms like ZStandard
(ZSTD), which offers more than 20 compression levels, where at level 1
it is almost as fast as LZ4, and where at higher levels it utilizes
computationally expensive techniques to rival LZMA at compression ratio
but trades off significantly for reduced compresson throughput. The ZSTD
level that should be set for a given column family or table will vary by
use case.

This change introduces provided compression codecs to HBase as
new Maven modules. Each module provides compression codec support
that formerly required Hadoop native codecs, which in turn relies
on native code integration, which may or may not be available on
a given hardware platform or in an operational environment. We
now provide codecs in the HBase distribution for users whom for
whatever reason cannot or do not wish to deploy the Hadoop native
codecs.

In some situations, a caller may know that it is properly managing the
Kerberos ticket to talk to HBase. In these situations, it's possible
that AuthUtil still tries to do renewals, but just fails repeatedly to
do so. Give a configuration flag for such clients to be able to tell
AuthUtil to simply stop trying.

Depending on which compression codec is used, a short read of the
compressed bytes can cause catastrophic errors that confuse the WAL reader.
This problem can manifest when the reader is actively tailing the WAL for
replication. To avoid these issues when WAL value compression is enabled,
BoundedDelegatingInputStream should assume enough bytes are available to
supply a reader up to its bound. This behavior is valid per the contract
of available(), which provides an _estimate_ of available bytes, and
equivalent to IOUtils.readFully but without requiring an intermediate
buffer.
Added TestReplicationCompressedWAL and TestReplicationValueCompressedWAL.
Without the WALCellCodec change TestReplicationValueCompressedWAL will
fail.

WAL storage can be expensive, especially if the cell values
represented in the edits are large, consisting of blobs or
significant lengths of text. Such WALs might need to be kept around
for a fairly long time to satisfy replication constraints on a space
limited (or space-contended) filesystem.
We have a custom dictionary compression scheme for cell metadata that
is engaged when WAL compression is enabled in site configuration.
This is fine for that application, where we can expect the universe
of values and their lengths in the custom dictionaries to be
constrained. For arbitrary cell values it is better to use one of the
available compression codecs, which are suitable for arbitrary albeit
compressible data.
