source-postgres: make withConnectionTimeoutMs configurable

[alafanechere]

Tell us about the problem you're trying to solve

The current connection to JDBC database is created with a hardcoded value for connectionTimeoutMsof 60000.
This can cause problems according to specific database setup and context.

Describe the solution you’d like

We could make the JDBC params override this value.
The withConnectionTimeoutMs builder method that changes the timeout is not used by any connector.

Can users set a timeout via optional JDBC parameters?

[anton-epsagon]

@grishick no, those seem to be ignored.
I'm currently trying to change the timeout value in airbyte-db/db-lib/src/main/java/io/airbyte/db/factory/DataSourceFactory.java locally to see if that helps

Hey team! Please add your planning poker estimate with ZenHub @edgao @ryankfu @subodh1810 @tuliren

Notes on testing:

• unit test should verify that the timeout is passed onto Hikari JDBC driver
• we should not be adding an integration test for this, because we are not testing the JDBC driver itself
