+/**
+ * Flink job entry point to launch a Beam pipeline by executing an external
SDK driver program.
+ *
+ * <p>Designed for non-interactive Flink REST client and container with Beam
job server jar and SDK
+ * client (for example when using the FlinkK8sOperator). In the future it
would be possible to
+ * support driver program execution in a separate (sidecar) container by
introducing a client
+ * environment abstraction similar to how it exists for SDK workers.
+ *
+ * <p>Using this entry point eliminates the need to build jar files with
materialized pipeline
+ * protos offline. Allows the driver program to access actual execution
environment and services, on
+ * par with code executed by SDK workers.
+ *
+ * <p>The entry point starts the job server and provides the endpoint to the
the driver program.
+ *
+ * <p>The external driver program constructs the Beam pipeline and submits it
to the job service.
+ *
+ * <p>The job service defers execution of the pipeline to the plan environment
and returns the
+ * "detached" status to the driver program.
+ *
+ * <p>Upon arrival of the job invocation, the entry point executes the runner,
which prepares
+ * ("executes") the Flink job through the plan environment.
+ *
+ * <p>Finally Flink launches the job.

Review comment:
@mxm any preference regarding class name? I first had it as
`FlinkPortableClientRunner` but maybe "runner" is misleading. On the other
hand, "entry point" is also redundant.

> Key: BEAM-8471
> URL: https://issues.apache.org/jira/browse/BEAM-8471
> Project: Beam
> Issue Type: Improvement
> Components: runner-flink
> Reporter: Thomas Weise
> Assignee: Thomas Weise
> Priority: Major
> Labels: portability-flink
> Time Spent: 2h 20m
> Remaining Estimate: 0h
>
> There are currently two methods to run a portable pipeline written in a
> non-JVM language to Flink:
> 1) Run the SDK client entry point which will submit the job server, which in
> turn will submit to a Flink cluster using the Flink remote environment
> 2) Run the SDK client entry point to generate a Flink jar file that can be
> used to start the Flink job using any of the Flink client tooling available.
> Either approach requires the SDK client and the job server dependency to be
> present on the client. This doesn't work well in environments such as
> FlinkK8sOperator that rely on the Flink REST API jar run endpoint (see
> [https://docs.google.com/document/d/1z3LNrRtr8kkiFHonZ5JJM_L4NWNBBNcqRc_yAf6G0VI/edit#heading=h.x7hki4bhh18l]).
> This improvement is to provide a new Flink entry point (main method) that
> invokes the SDK client entry point to generate the pipeline and submits the
> resulting Flink job like any other Flink native driver program would, via the
> optimizer plan environment ("[auto]").
