[Feature Request]: Cache the BigQuery table definition instead of calling tables.get() from every worker #34076

Description

@PraveenAkunuru

What would you like to happen?

When calling BigQuery's tables.get method, today, we are calling it from every Dataflow worker. This is resulting in customers hitting Quota issues. Please can we cache the Table definition and re-use for all workers instead of calling the method from every worker.

https://cloud.google.com/bigquery/docs/reference/rest/v2/tables/get

table = bq.get_table(
table_ref.projectId, table_ref.datasetId, table_ref.tableId)

response = self.client.tables.Get(request)
