URL: https://github.com/apache/beam/pull/17222


   The overall project is to remove watermark updates to the metadata table from the Connector. To do so, we need to create a new restriction tracker that keeps track of partition token state, as well as timestmap.
   
   The purpose of this PR is to create the new restriction tracker that keeps track of both state and timestamp information.
   
   The overall algorithm to remove watermark updates to the connector metadata table is here: https://docs.google.com/document/d/1YqpR2iiHV5ESPBg24y_BUuSKYcsgYKDhpxyNoAUzP68/edit?resourcekey=0-m4Rif7BtMjN4OxTzXbMC3g&disco=AAAAWDcj4KU
   
   The design for the new restriction tracker is here: https://docs.google.com/document/d/1lSLOPSiJFUV2Tr7plSQXn-DcyBNgV5ELJ8p9PRpcO2c/edit?resourcekey=0-tXh0F0I9HK30XV9a7hnfiw
