IMPALA-5156: Drop VLOG level passed into Kudu client

The Kudu logging is very verbose and all of the logging may
affect performance. This change reduces the Kudu client log
level to v-1, since Impala is typically run at v=1 and isn't
too noisy.

In some simple concurrency testing, Todd found that reducing
the vlog level resulted in an increase in throughput from
~17 qps to 60qps.
