Description

Both  bin/solr and bin/solr.cmd have lots of shell code to parse the zk sub commands, and to print the usage text. We have both a short zk uage text and the full one.

Usage: solr zk upconfig|downconfig -d <confdir> -n <configName> [-z zkHost] [-s solrUrl]"
       solr zk cp [-r] <src> <dest> [-z zkHost] [-s solrUrl]"
       solr zk rm [-r] <path> [-z zkHost] [-s solrUrl]"
       solr zk mv <src> <dest> [-z zkHost] [-s solrUrl]"
       solr zk ls [-r] <path> [-z zkHost] [-s solrUrl]"
       solr zk mkroot <path> [-z zkHost] [-s solrUrl]"
       solr zk linkconfig --conf-name <confname> -c <collection> [-z zkHost] [-s solrUrl]"
       solr zk updateacls <path> [-z zkHost] [-s solrUrl]" 

Extend SolrCLI and tools API to handle sub commands more natively so that doing solr zk -h shows a list of sub commands, while `solr zk cp -h` shows usage for that sub command.

I think commons-cli does not have native subcommand support like e.g. picocli, but it should be possible to implement..
