Support other database integrations like Oracle for dagster storage

[amaralvieira]

Hi! Right now we can use MySQL and PostgreSQL for dagster storage (events, runs, scheduler).

With support for other databases (in my case I would be interested in Oracle), teams could more rapidly develop production-grade pipelines without the limitations of SQLite: all too frequent "database locked" errors, no retries... An example: when developing locally I have to limit the dbt threads otherwise the dagster runs often fail on SQLite concurrent writes, while the dbt runs have succeeded.

It is probably a stupid question, but would a more generic dagster db adapter work, even with any caveats of not being optimised for any particular db? It is already sqlalchemy under the hood.

I would be happy to test, especially for anything Oracle related.
