Extend the Context with an ExecutorService

[FDelporte]

Different approaches should be possible

• User can inject his own executor service into the Context
• The Context needs to create its own ExecutorService if none is provided

This ExecutorService is needed for

• DigitalOut Blink
• DigitalOut Pulse

Multi-threaded capability and implementations of the asynchronous APIs would be a terrific step forward!

I assume this would require some non-trivial changes to provide the necessary thread safety, correct?

Indeed @tcfurrer will have some impact. I have been looking into this in the past.

It would all start with defining the ExecutorService in the context https://github.com/Pi4J/pi4j-v2/blob/develop/pi4j-core/src/main/java/com/pi4j/context/Context.java

And could be used to handle for instance thread actions like pulsing a LED https://github.com/Pi4J/pi4j-v2/blob/develop/pi4j-core/src/main/java/com/pi4j/io/gpio/digital/DigitalOutputBase.java#L102

These are only a few first steps and to be further investigated where and how such multi-threading should be applied.

Here would be an ideal place to discuss this functionality.
