[BZ 970784] After successful bundle deployment, discover new resources

After a successful bundle deployment, initiate resource discovery for all the affected resources. This should ensure that user doesn't have to manually add new resources to their inventory (or force discovery process).
Just for the sake of API stability and avoidance of any possible future headaches, I think we should strive for as little API changes as possible.

A non-zero delay is solely used by agent side code so an overload of this method directly on the InventoryManager class should be enough. You won't have to declare the API change and also won't have to change the server side code.

In this case, it is mostly just nitpicking but IMHO we should develop the habit of avoiding API change whenever possible (i.e. a reason for an API change should be more than just "I needed it to fix a bug" - it should be found unavoidable and the consequences should be understood).
