Removed the dependency of tez input context on the interface.

> HiveSplitGenerator is tightly coupled with Tez's InputContext to fetch the
> available slots during split calculation. Creating a interface to fetch the
> available slots will allow having other implementation too which are more
> suitable for different cloud vendors.
> The idea is to have a default implementation using Tez's InputContext and a
> new HiveConfiguration pointing to the class implementing the interface.
> Different cloud vendors can plugin there strategy by implementing the
> interface.
