interop/lb: Increase Go PSM LB test timeout to 300min

[sreenithi]

Increased timeout of the LB test suite to 5 hours

Reason for increase:
The LB test suite (xds_k8s_lb tests) have been failing with a 3 hour timeout over the past 2 weeks, with the following error message: Aborting VM command due to timeout of 10800 seconds

This error was also observed for other gRPC languages like Java, Python and Node, and similar PRs have been raised in the respective language repos.

RELEASE NOTES: None

@sreenithi can you mention the reasoning behind the change in the PR description for future reference?

Also is there someone among the maintainers who's familiar with the issue at hand who I can add assign as the reviewer?

[purnesh42H]

Is the same change done to increase for all the languages?

[sreenithi]

@arjan-bal The LB test suite (xds_k8s_lb) have been failing with a 3 hour timeout over the past 2 weeks, with the following error message: Aborting VM command due to timeout of 10800 seconds.
So Sergii suggested to increase the timeout of the tests.

And I'm not sure of the relevant maintainer, possibly Arvind or Doug, whoever also knows about the PSM Interop tests should be a good choice.

@purnesh42H This change is specific to Go, but I've raised separate PRs in the respective repos for Java and Python as well.

oh yeah i meant if you are changing for all languages. Can mention the languages in description. I don't think we should link internal issues here

[sreenithi]

ok, I have updated the PR comment as you suggested.

[purnesh42H]

nit: pr title can be test: increase psm-interop-test timeout to 300m from 180m. Also, might be good to link the PRs of java and python here for reference
