Flink task lifecycle listener/hook/SPI

[Allen Zoo]

Hi all,
We went to do some init env setup before the flink task run, And we have
noticed the Task Lifecycle | Apache Flink
<https://nightlies.apache.org/flink/flink-docs-master/docs/internals/task_lifecycle/>
doc
described, but we can't find  listener/hook/SPI interface do some custom
init jobs before task  running. Does flink now have relevant interfaces ?
