[Feature Request] Ignore specific source columns

[AaronCoquet-Easypark]

I have a project that uses Fivetran (and some other tools) to sync data to Snowflake as sources for dbt. I don't want to include certain columns (_FIVETRAN_SYNCED, for example), since they're not terribly useful for our use case. I'd like to be able to configure dbt-osmosis to not inject them for every single source.

Added in latest release 0.12.1

You can leverage this via adding a _blacklist key to your dbt-osmosis vars config as so:

# dbt_project.yml

vars:
  dbt-osmosis:
    _blacklist: ["columns", "to", "exclude", "[Rr]egex.*is_ok"] # <- this is the new reserved key
    <source_name>: <path>
    <source_name>:
      path: <path>
      schema: <schema>
