[FLINK-9852] [table] Expose descriptor-based sink creation
## What is the purpose of the change
This commit exposes the new unified sink creation through the table
environments and the external catalog table. It introduce a new `update-mode`
property in order to distinguish between append, retract, and upsert table
sources and sinks. This commit refactors the top-level API classes a last time
and adds more documentation. This commit completes the unified table
sources/sinks story from an API point of view.
## Brief change log
- Introduction of `TableEnvironment.connect()` and corresponding API
builder classes
- Introduction of property `update-mode: table` and update of existing
connectors
- External catalog support with proper source/sink discovery and API
