ProvideServiceEvent to allow other implementations

[0utplay]

Describe the new feature

Create a new ProvideServiceEvent that is called when a service from the ServiceRegistry is requested. This event should provide a way to override the choosen service so that the user can decide if a different implementation then the one choosen should be used.

Why do you need this feature?

Users should be able to provide other implementations than the default impl
