* fix: avoid possible job already exists error

If job create request fails, a query job might still have started
successfully. This commit handles this edge case and returns such
query job one can be found.

* Catch only Conflict errors on query job create

api-core, cloud-core, and resumable-media wil all be releasing Python3-only
2.x versions shortly.

Closes #767.

…google-resumable-media` (#770)

**Note**: PR is empty because this is purely to make sure CHANGELOG is updated. Follow-up to #768

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://github.com/googleapis/python-bigquery/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)

Fixes #767  🦕

…P fields (#736)

* feat: add LoadJobConfig.projection_fields to select DATASTORE_BACKUP fields

* add type annotations

* annotate setter too

Co-authored-by: Peter Lamut <[email protected]>

* feat: add support for more detailed DML stats

* Move is None check of DmlStats one level higher

…ge (#748)

* refactor: omit `read_session` with latest google-cloud-bigquery-storage

`read_session` is unnecessary as of `google-cloud-bigquery-storage>=2.6.0`.
This will allow us to more loudly deprecate the use of `rows(read_session)`.

Rather than require 2.6.0, version switches will allow us to keep our
requirements range wider. Will want to give this version some time to bake
before making it required.

* optimize _verify_bq_storage_version

* fix failing tests due to optimization

* fix unit tests

* create BQStorageVersions class for version comparisons

* add type annotations

Also, use packaging directly, since that's all pkg_resources does

* allow legacy versions

* fix coverage

* fix coverage

* add tests for version helpers
