[jclouds/jclouds] JCLOUDS-1368: Simplify slicing algorithm (#1166)

[Andrew Gaul <no...@github.com>]

Previously `MultipartUploadSlicingAlgorithm` sliced larger payloads into
a number of fixed-sized parts and a single variable-sized last part.
Callers did not account for the last part which lead to exceeding the
maximum number of parts in `BaseBlobStore.putMultipartBlob`.  Simplify
the interface by removing the remaining concept and simply split the
parts into even sizes.  This improves performance by eliminating
pathological cases with very large last parts.

Re: [jclouds/jclouds] JCLOUDS-1368: Correct use of slicing algorithm (#1166)

[Andrew Gaul <no...@github.com>]

I reworked this commit to correct the use of the slicing algorithm.  [JCLOUDS-1369](https://issues.apache.org/jira/browse/JCLOUDS-1369) tracks improving the algorithm itself.
