v0.5.0

Full Changelog: v0.4.1...v0.5.0

This release includes testing expansion to dbt 1.4 as well as a change in how we handle the default provider. By default, feature_flag calls will now be translated directly to var calls. This will lets users seamlessly go between testing and live environments with minimal code change. The source of the flags will simply shift from a static dbt_project.yml to your provider of choice such as harness.io
