AbortMPU to properly cleanup existing s3 object

- CompleteMPU was and is still, at the time of this commit,
  wrongly promoting s3 objects when completing a MPU even if
  the parts are not valid.
- The AbortMPU cleanup logic was added as an effort to cleanup
  new occurences of this problem, and still handle old ones not
  yet aborted.
- The logic currently is unable to clean up if the current
  master version has a different upload id: in case a new version
  was pushed, we end up never cleaning the ghost.
- This commit introduces a dynamic listing of the versionIDs of
  the object. We use the delimiter versions algorithm and the
  versionID separator to list only the current object versions,
  with pagination support, and then we detect the one to cleanup.
