Feature Request: Support for column-level databricks tags

[stevenayers]

Describe the feature

The new support for Databricks tags on tables & views is really useful. Any chance of supporting column tags too? This is useful for tagging columns that contain particularly sensitive data.

In the same way that tags sits under config on a model, but tags is a top-level attribute on columns:

models:
  - name: foo
    description: I'm a teapot
    config:
      tags:
        - hourly
      databricks_tags:
        - foo
    columns:
      - name: id
        tags:
          - bla
      - name: bank_details
        tags:
          - bla
        databricks_tags:
          - don't publish this column on the internet please
      - name: date
        data_type: date

Are you interested in contributing this feature?

Sure, let me know if how I've designed the spec in YAML looks good, and I'll raise a PR for the feature.
