Databricks isn't using the name "virtual clusters" anymore, I believe they're just calling them "endpoints."
Rather than a combination of cluster and cluster_type, I think we should make the distinction between cluster (old style, all-purpose/interactive) and endpoint (new style). Users should specify either a cluster or an endpoint when connecting via odbc.

I landed on pip install dbt-spark[ODBC] because pyodbc is the only python dep that I imagine will require OS dependencies. Also, I think this should line up with connection methods (thrift, http, odbc), rather than connection locations (Databricks, etc..)?

Eventually, I think we might want to try moving PyHive[hive] as an extra instead of principal requirement, since it's only necessary for the http connection method.
Justification: we see some installation errors (e.g. #114) resulting from less-maintained dependencies exclusive to PyHive
Not something we need to do right now!

Resolves #104
Description
Add support for ODBC driver connections with Databricks via cluster specific path and sql endpoint path.
