[Discuss] Rename Catalog class
Hi all,
As we are working on multi-catalog feature.
The concept `Catalog` is used as an internal or external "data source". This word is also used in other project like Spark and Presto, even in MySQL.
But in Doris source code, we had a class called "Catalog.java". But actually, it is more like an Env or Runtime class.
To resolve the name conflict, I suggest to rename the Catalog class to a new name, I prefer DorisRuntime or DorisEnv.
And because this class is used everywhere in source code, so I think it is necessary to discuss its new name.

I would like to just use a short name: `Env`.
If there is no other question, I would like to modify it next week

Actually, it is not a "meta". It is more like a unified entrance to access other modules, like a set of managers(LoadManger, AlterHanlder, etc).
And you can see it is a singleton.
