Are we planning to change the existing timeout? How will this be controlled from user perspective?

This option provides the flexibility to override the existing timeout, it is optional because we most of platforms' performance are good enough to create switch within default timeout.

The timeout setting can be controlled by platform designer, e.g. https://github.com/sonic-net/sonic-buildimage/pull/19928/files

As the change is in main() passing a new argument to orchagent, found we that we are doing a similar argument change in this test case. This change does not affect the behavior of the test as timeout value we are sending is still same as default(60 sec). But helps to cover the UT for new code change.
