LifecycleAwareStarts a service or component.
Implementations should determine the result of any start logic and effect
the return value of LifecycleAware.getLifecycleState() accordingly.

ConfigurableRequest the implementing class to (re)configure itself.
When configuration parameters are changed, they must be reflected by the component asap.
There are no thread safety guarantees on when configure might be called.

public PollableSource.Status process()
PollableSourceAttempt to pull an item from the source, sending it to the channel.
When driven by an EventDrivenSourceRunner process is guaranteed
to be called only by a single thread at a time, with no concurrency.
Any other mechanism driving a pollable source must follow the same
semantics.
