> NettyAvroRpcClient performs unnecessary hostname lookups

> When NettyAvroRpcClient works with a host that has only an IP address
> associated with it but no hostname, some operations take too long (a few
> seconds vs expected millis). This affects most of exceptions throwing and a
> part of logging.
> This happens because of the unnecessary and expensive hostname lookup when
> converting NettyAvroRpcClient to String.
