Attachment: Bug 1663707 - Support multiple modes for IOUtils.write methods r?gijs,emalysz

IOUtils.write{,UTF8,JSON} now support multiple writing modes:

• overwrite, where the contents of the file will be overwritten and a new file
  will be created if it does not exist (the old default),
• create, where the file cannot exist and it will be created during the
  operation; and
• append, where the file will be appended to.

Depends on D111734
