Trace table ExecService invocations as table operations. Ensure span relationships for both table
and master invocations.

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
flexible definition.

For batch operations, collect and annotate the associated span with the set of all operations
contained in the batch.

Change scan caching back to 1 to avoid extra work at Region Server side. For most cases, the extra 4 results
fetched are wasted at the client side.

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.

For unit testing in sync connection with OpenTelemetry tracing,
there is a race condition between ConnectionImplementation#finalize
(object GC) and the test method before Rule triggered by
OpenTelemetryRule.create. such that a error message of
`GlobalOpenTelemetry.set has already been called`.
This change fixed it test by moving up the TRACE_RULE creation
to class-level such that the GlobalOpenTelemetry is being set
and reuse it for all methods.
