> Add full tika-pipes support of grpc
>  * pipe iterator
>  * fetcher
>  * emitter
> Requires we create a service contract that specifies the inputs we require 
> from each method.
> Then we will need to implement the different components with a grpc client 
> generated using the contract.
> This would enable developers to run tika-pipes as a persistently running 
> daemon instead of just a single batch app, because it can continue to stream 
> out more inputs.
