Allow configuring the format of EventTimeFilter

[logicoffee]

ref: dbt-labs/dbt-core#11331
docs dbt-labs/docs.getdbt.com/#

Problem

Currently, EventTimeFilter is formatted as YYYY-MM-DD HH:MM:SS+00:00. However this format is not suitable for the following cases:

• referencing tables where event_time isn't of type timestamp (especially in BigQuery).
  • For BigQuery, it's addressed by Fix: Cast to timestamp prior to event time comparison dbt-bigquery#1422.
  • But casting event_time to timestamp causes a full scan.
  • When event_time is of type date, it's preferable to filter referenced tables using event_time > 'YYYY-MM-DD'
• referencing sharded tables (especially in BigQuery).
  • Daily sharded tables are usually have a suffix like 'YYYYMMDD'.
  • It's better to filter referenced tables using _table_suffix > 'YYYY-MM-DD'.

Solution

Added format configuration to EventTimeFilter.
Interface will be updated by dbt-labs/dbt-core#11376.
