add WatchService to KnServingClient interface

[ericmillin]

Feature request

Expose the WatchService function via KnServingClient interface. This will make the function available to users outside the project.

Use case

I want to use the kn client to watch services in my own code

Not sure if this is already implemented but I still think it is a good idea :-)

I think we have now a WatchServiceWithVersion but its not part of the interface (however, a public method). @dsimansk do you think it makes sense to move that to the client interface (and maybe rename it to WatchService ?)
