simplify process of setting up background publishing

Based on a number of the recent issues:

#141
#130

It can be quite confusing to get the background poll and publish tasks setup and running in a way that is intuitive. I think we can find a way that would work for most users without them having to worry about all the details for how and why some of this stuff works. For example, right now are default examples don't mention anything about the poller reset which can lead to getting an accumulated value for the life of the application.

We are not investing in significant improvements to servo.
