AbsoluteDeadband and PercentChange to exclude data samples

Data Filtering in the Adapters allows you to define what change in data must occur for the data to pass filtering and be egressed by the Adapter. It would also be useful to employ filtering for data quality applications - such as if the value changes by too much it is considered invalid and don't pass filtering to be egressed. This would allow the adapter to filter spikes in the data, incorrectly collected values, impossible values, etc. before they even get sent to PI. As a specific use case for this is a customer who is monitoring pipe wall thickness erosion - which would never increase. If the value increased above a certain threshold they can be certain it is a mismeasurement and should be discarded.
