Highlights

• Configuration Updates: Added new configuration options for Bigtable read row timeouts to the BigtableToParquet template.
• Timeout Customization: Introduced 'Read rows attempt timeout' and 'Read rows operation timeout' parameters, both defaulting to 5 minutes.

Code Review

This pull request introduces configurable timeouts for Bigtable read operations in the BigtableToParquet template by adding 'readRowsAttemptTimeout' and 'readRowsOperationTimeout' to the pipeline options. Feedback suggests using 'ValueProvider' for these new options to maintain consistency with the existing codebase, as well as adding '@SuppressWarnings("unused")' to setters and marking the template parameters as optional.
