[ELE-1257] Support Dremio

[maxfirman]

Is your feature request related to a problem? Please describe. We use Dremio and DBT at work and would like to use elementary for storing project artifacts and test results.

Describe the solution you'd like Elementary to support Dremio.

Describe alternatives you've considered N/A

Additional context N/A

Would you be willing to contribute this feature? Yes, in fact I have made some limited progress already.

I have managed to get dbt run --select elementary to execute without errors against our Dremio DBT project.

I'm currently working through the e2e tests here. There are still lots of errors at the moment, but I can raise a PR once I've ironed them out.
