Description

• core-default.xml updated so that fs.s3a.committer.magic.enabled = true
• CommitConstants updated to match
• All tests which previously enabled the magic committer now rely on
  default settings. This helps make sure it is enabled.
• Docs cover the switch, mention its enabled and explain why you may
  want to disable it.
  Note: this doesn't switch to using the committer -it just enables the path
  rewriting magic which it depends on.
