Description

The Python table Api offers three table environment:

• TableEnvironment
• StreamTableEnvironment
• BatchTableEnvironment

The `TableEnvironment` pydoc states that it a unified interface for pure table applications. However, it is currently missing a public constructor or `create` method to instantiate. This method should be added so users can leverage a unified interface and to better align pyflink with the JVM table apis.
