Stress test: Fix stack trace collection
A lot of stuff got messed up during the switch to the cluster model...
Changes:
1) find_crashed_impalads() returned a list but the caller expected a
dict.
2) for_each_impalad() ignored the parameter 'impalads' and instead used
all impalads in the cluster.
3) find_last_backtrace() returned the oldest core dump instead of the
newest.
4) num_successive_errors_needed_to_abort was effectively hard-coded to
2. I'm not sure how that happened.
5) Catch EOFError when getting a query from the work queue. This happens
when the work queue is shutdown but there are workers waiting for an
item.
6) Ignore connection errors due to an unresponsive impalad. When the
load on an impalad get very high it randomly stops responding to
client requests. Reducing the load seems to help.
7) Added various log messages.
