Michael Brown 481988fcea IMPALA-2721: EE statestore tests: increase subscriber failure timeout threshold ...

Some end-to-end statestore tests are failing when Impala is built for
code coverage. The failures are due to the statestore's not detecting
disconnected subscribers within 20 seconds. In some of the failed tests'
logs we see subscribers lingering for up to 30 seconds. Local
reproduction attempts failed to reproduce such long subscriber
lifetimes.

To unblock failing builds, the simple fix here is to increase the
timeout. The full details for choosing simply to increase the timeout
are in IMPALA-2721. IMPALA-2886 tracks further investigation into why
the 20 second timeout isn't sufficient and why local reproduction wasn't
possible.

Testing:

In addition to testing described in IMPALA-2721 to justify increasing
the timeout, I ran a full private code coverge build in Jenkins. Tests
that were failing before now pass:

- test_failure_detected
- test_topic_persistence
