[feat]: Right Click - Copy Keyspace Schema

[millerjp]

We need to give uses the ability to copy a schema for a keyspace and recreate it under a new name. All the users can do in this sitiation is choose a different keyspace name and replication factor settings. All of the tables, views, indexes, udts etc.. need to be copies as is a recreated under the new keyspace name.

Add an option to Copy Keyspace Schema when right clicking on a specific keyspace

Goal here is simple solution - everything is the same only thing that can be changed is keyspace name and settings.
