Description

ZooKeeper currently depends on netty-all to satisfy the requirements for the SSL capability.
netty-all is an unnecessarily broad dependency, we already had request to revise (https://issues.apache.org/jira/browse/SOLR-13665)

netty-handler (429KB) and netty-transport-native-epoll (115KB) looks like is enough.
Netty-all was ~4MB.
This reduce size of netty dependency to 1/8.
