why do we need 30 retries? we should expect exact one retry, right?

I had 30 retries in case request never fails (try up to ~3-sec), or the error is transport is closing which takes more than 100ms to recover(endpoint switch)--so it takes more than 1-retry to succeed.
Changed the logic to test with only one retry after failure, by giving more wait time.

grammar nit: "...expects that when the member of the pinned endpoint is shut down, the balancer switches its endpoints and all subsequent..."

Potential source of test flakiness? Is there a condition we can poll for that would be more reliable?
