consolidate InfoViewer and PropEditor

[ArbaazKhan1]

Closes issue #6428

Created a new zk props command to consolidate ZooKeeper property inspection and editing. Both legacy commands are depreciated but remain and functional for backwards compatibility. The new zk props core sub-commands operate as such:

• Default / scope flags (-t, -ns, -r) --> reproduces ZooPropEditor single-scope print output
• --set, set a property for the resolved scope
• --delete, delete a property for the resolved scope
• --get, reproduces ZooInfoViewer --print-props multi-scope report, using --system, --namespaces, and --tables filter flags

If I'm understanding things correctly here, I think we should be rejecting --tables and --namespaces for --set and --delete as opposed to whats happening now: only when --get is absent.

Suggested change

	if ((!systemOpt || !namespacesOpt.isEmpty() || !tablesOpt.isEmpty()) && !getOpt
	&& setOpt.isEmpty() && deleteOpt.isEmpty()) {
	if (!namespacesOpt.isEmpty() || !tablesOpt.isEmpty()) {
	throw new IllegalArgumentException("--namespaces and --tables are only valid with --get");
	}
	}
	boolean isMutating = !setOpt.isEmpty() || !deleteOpt.isEmpty();
	if (!namespacesOpt.isEmpty() || !tablesOpt.isEmpty()) {
	if (isMutating) {
	throw new IllegalArgumentException(
	"--namespaces and --tables are not valid with --set or --delete");
	}
	if (!getOpt) {
	throw new IllegalArgumentException("--namespaces and --tables are only valid with --get");
	}
	}

--get advertises the ability to accept --table and --namespace as well but only the plural tables and namespaces opts are copied.
