feat: add tracing for batchUpdate, executeUpdate, and connections

[olavloite]

• Adds OpenTelemetry tracing to the Connection API. This again enables tracing in the JDBC driver and PGAdapter.
• Adds traces for batchUpdate calls in the Java client library (these calls were not traced).
• Adds traces for executeUpdate calls in the Java client library (these calls were not traced).
• Adds an option to include the actual SQL statement that was executed with the trace. This option is disabled by default. The option is named enableExtendedTracing, and might include additional features in the future.
• Adds the transaction tag and statement tag as attributes to the OpenTelemetry traces. This makes it easier to find traces for specific transactions and statements.

We should also update the Readme OpenTelemetry about the new Environment Variable and Option
