feat(ingestion/tableau): hidden asset handling

[haeniya]

Description

This PR enables the configuration of how to handle hidden assets in Tableau. Views and Dashboards can be hidden within Workbooks. Hidden assets can be identified by a missing/blank luid, as stated in the documentation: https://help.tableau.com/current/api/metadata_api/en-us/reference/view.doc.html

This PR introduces two new config properties tags_for_hidden_assets and ingest_hidden_assets to better control what to do with hidden assets. They can either be skipped completely or tagged.

Configuration in the recipe could look like this:

source:
  type: tableau
  config:
    # Coordinates
    connect_uri: https://tableau.example.com

    # Handling of hidden assets
    tags_for_hidden_assets: ['private', 'hidden']
    # or completely skip hidden assets with
    # ingest_hidden_assets: False   

    # Credentials
    username: "${TABLEAU_USER}"
    password: "${TABLEAU_PASSWORD}"

sink:
  type: "datahub-rest"
  config:
    server: "http://localhost:8080"
