Migrating over @gkevinzheng PR from bigtable monorepo googleapis/python-bigtable#1238

Original description:

Changes:

  • Added a new property new_table_data_client _veneer_data_client in the classic client for the new table data client
  • Added two hidden kwargs (client_info and disable_background_channel_refresh) to the new data client constructor to support the classic client.

Fixes #15298

Note to reviewers: This PR has already been reviewed and merged to a staging branch, with the intention of doing a single merge to main. We are now planning to slowly rollout these changes back to the main branch. Minimal re-review should be necessary

Additional system tests for testing shim compatibility with the classic
client interface.

Also fixes a bug where encountering a retriable error after another
retriable error mid-stream raised an exception instead of retrying.

Fixes #1156

Changes:
- Added a new property `new_table_data_client` (might need to be
renamed) in the classic client for the new table data client
- Added two hidden kwargs (`client_info` and
`disable_background_channel_refresh`) to the new data client constructor
to support the classic client.

Fixes #1157
