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

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

[ArbaazKhan1]

The singular --namespace / --table and plural --nampespaces / --tables are intentionally separate. They are intended to serve the different modes. The singular flags are meant to display a singular Zk scope for --set and --delete or default display, while the plural is used for filtering multi-scope ZK reports via --get.

[DomGarguilo]

If the split is intentional then I agree tht we should keep them. In that case, I think the --get accepts the singular flags and silently ignores them. It might be better to reject the -t under --get and tell the user to use --tables. Hopefully im interpreting things correctly here
