[kudu-admin-test] improvements on error reporting

This changelist introduces improvements on logging in case
if an assertion triggers in the rebalancer-related scenarios.

I found it's hard to troubleshoot the flakiness reported lately
in the RebalancerAndSingleReplicaTablets.SingleReplicasStayOrMove
scenario.  With hindsight, it turned out that improved logging
on assertions would help a lot.
