feat: add a flag to add / remove routing cookie from callable chain (#2032)

Test and rollback plan: [go/cbt-routing-cookie-rollback](http://goto.google.com/cbt-routing-cookie-rollback) Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly: - [ ] Make sure to open an issue as a [bug/issue](https://togithub.com/googleapis/java-bigtable/issues/new/choose) before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea - [ ] Ensure the tests and linter pass - [ ] Code coverage does not decrease (if any source code was changed) - [ ] Appropriate docs were updated (if necessary) - [ ] Rollback plan is reviewed and LGTMed Fixes #<issue_number_goes_here> ☕️ If you write sample code, please follow the [samples format]( https://togithub.com/GoogleCloudPlatform/java-docs-samples/blob/main/SAMPLE_FORMAT.md).
