Support BigQuery 'labels' and 'hours_to_expiration' configs for seeds

[darrylng]

resolves #125

Description

This PR enables +labels: and +hours_to_expiration: configs for seeds configuration. These labels are already implemented and used by models configuration to set table/view labels and expiration time, but was not done for seeded tables, reasons explained in issue #125.

The initial change was to only implement labels config but on further dev, I noticed the addition of ALTER TABLE .. SET OPTION() supports other options other than labels, so the pytest was added to include hours_to_expiration config test as well.

These are the only two non-configs properties that are currently implemented in dbt-bigquery that will start to take effect with the change in seed.sql.

Hi @darrylng sorry for the wait on review if you could update to current main and push up to clear up current conflicts that would be great as it keeps your local in step with your pushed up pr.

@darrylng it seems that we have added the pre-commit since you last updated, if you could update your local and run the pre-commit checks to make sure its passing should clear up the code-quality test. sorry for the delay in response.

@darrylng really liking this tested locally and tests are passing, not sure why more aren't triggering here. if you could please update to latest in main and re push up (want to just keep your remote and local up to date with each other). but this is looking very good thus far great work!

I have merged main branch into my forked branch but I believe the three tests that aren't running is because I'm a first time contributor and the workflow requires a maintainer to approve running it.

Any chance we can get this reviewed? I'd love to see this feature soon as the current patchwork involves running macro to add labels after on-run-end which runs for all dbt commands. Thanks for your support all!

Any news on this request ?
It would be appreciated to clean seeds after ci jobs.
Thanks!
