Support options property in PostgreSQL connector

[takezoe]

Description

PostgreSQL JDBC driver can take options property to send connection initialization parameters to the PostgreSQL server which allows clients to specify the statement timeout, etc.

It would be great if we can specify those parameters for connections from Trino.
