Review comment:
It is a bit confusing to expose retrivalToken as part of the JobInvocation
and will not be used by JobInvocation users.
Based on the following comment to make JobInvocation a concrete class, we
can just keep retrieval token in FlinkJobInvocation.

> Key: BEAM-6725
> URL: https://issues.apache.org/jira/browse/BEAM-6725
> Project: Beam
> Issue Type: Task
> Components: runner-flink, runner-samza, runner-spark

> Assignee: Kyle Weaver
> Priority: Major
> Labels: portability
> Time Spent: 3h 20m
> Remaining Estimate: 0h
>
> Like BEAM-6714, FlinkJobInvocation contains some code (for asynchronously
> running jobs) that isn't really Flink specific and therefore could/should be
> reused by other portable runners. I'm thinking instead of an interface,
> JobInvocation should be made an abstract class that implements the methods
> that it currently abstracts, with an abstract method `runPipeline` for the
> runner-specific details.
