Cleanup FileSplit and FileReference

This change gives FileSplit and FileReference specific meaning to
avoid confusion of an absolute vs relative, local vs global, inside
an IO device vs outside IO devices.

In addition, it enables better abstraction of global partitions and
delegate the responsibility of choosing which partition goes to which
IO device to the IO Manager through the introduction of FileDeviceComputer

In details:
Previously, the LocalResource in Hyracks had partition (storage partition)
and there is no such thing in Hyracks. This scope leak is bad. In addition
The local resource had a name and a path. they were always the same and so
the name was removed.
The storage partition was instead moved to asterixdb implementation of the
serialized object in the local resource.

With all of these changes, the cluster controller (compiler) only needs to
know about partitions and relative paths. It doesn't need to worry about
heterogenous Node setups and different io device configurations. For File
assignment to IO devices, a new interface (IFileDeviceComputer) was
introduced which can be overriden by applications to have their own
strategy for distributing files among IO devices.
