[rpc-test] fix flakiness in TimedOutOnResponseMetricServiceQueue
Before this patch, the TestRpc.TimedOutOnResponseMetricServiceQueue
scenario would fail from time to time (about once in every 100 runs)
when running on a VM in AWS cloud with error message like below:
src/kudu/rpc/rpc-test.cc:1499: Failure
Value of: s.IsTimedOut()
Actual: false
Expected: true
Remote error: Got some error
I haven't seen it if running on nodes backed by a dedicated hardware,
and I guess that's due to scheduler anomalies induced by shared virtual
environment. However, I didn't look deeper and just increased the sleep
time 10x and added 2x margin for RPC timeout. With this patch, there
hasn't been a single failure in more than 10K runs of the test scenario.
The scenario still runs quite fast on modern hardware: less than 500ms.
