[2/3] kudu git commit: Reduce log spew from rpcz_store.cc

[al...@apache.org]

Reduce log spew from rpcz_store.cc

The sampled RPC call statement has been filing the log. Let's dial down its log level.
This particularly impacts Impala as its default log level is 1.

If it turns out that this log statement is useful for Kudu deployment, we can
consider doing this change in Impala only.

Testing done:
  ctest -R rpc-test;
  Built debug and release builds;
