Feature/insert-manager

This PR simplifies the controller logic by introducing a new class InsertManager.
InsertManager holds a list of possible Filters which filter keys based on OS, AppVersion or features activated.
The Filters are added at startup in the WSBaseConfig and allow for Filter activation by Profile or Property.

Additionally, the InsertManager can be configured with modifiers.
Modifiers can be used to modify keys before inserting into the datbase.

Replaces the previous g811a8d461394eecd25bd190c01b933cc177b7d05, according to #226
