Replace dagster_airbyte load_assets_from_airbyte_project

This worked really well for a large number of airbyte connections. It is significantly more performant than load_assets_from_airbyte_instance and shortens dagster start times. (I had a use case where dagster startup just timed out on me when I tried to use load_assets_from_airbyte_instance.)

However, it relies on the octavia file structure. Airbyte has removed octavia completely, in favor of their new (if a little buggy) terraform provider. As such, we need a new way to define local airbyte connections. I was able to build a local implementation that wraps build_airbyte_assets easily enough, but I'm wondering if we should build an official way to extract information from terraform state files (I just duplicated). Additionally, we should probably update docs/deprecate the asset loader that depends on octavia
