The Port GCP BigQuery data source only contains a subset of the fields available in https://cloud.google.com/bigquery/docs/reference/rest/v2/tables. Some useful fields that are currently missing in Port are:

- column metadata (from https://cloud.google.com/bigquery/docs/reference/rest/v2/tables#TableSchema - including name, description, type and any policy tags)

- numRows

- lastModifiedTime

Why: I'd like to use Port as a Data Dictionary, and so it will be useful to have as much information about tables as possible.
