[FLINK-34079] FLIP-405: Migrate string configuration key to ConfigOption

• Type: Improvement
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Fix Version/s: 1.20.0
• Component/s: Runtime / Configuration

Release Note

We have deprecated all `setXxx` and `getXxx` methods except getString(String key, String defaultValue) and setString(String key, String value), such as: setInteger, setLong, getInteger and getLong etc. We strongly recommend users and developers use get and set methods directly.

In addition, we recommend users to use ConfigOption instead of string as key.
