Description

FLINK-32023 changed the `ExecutionOptions.BUFFER_TIMEOUT` to `ExecutionOptions.BUFFER_TIMEOUT_INTERVAL`, the filed name should be reverted.

Because the `ExecutionOptions` is a public evolving API, some flink users are using the `ExecutionOptions.BUFFER_TIMEOUT` in their code. If we update it, the code cannot upgrade to 1.18 directly.

 

BTW, the option name is changed from `execution.buffer-timeout` to `execution.buffer-timeout.interval`. However, we marked the `execution.buffer-timeout` as `DeprecatedKeys`. So 1.18 is compatible with the old option name.
