#1004 Add new fields to /image/create response

Extend ogClient to include more information about the image that has been
created. This patch modifies ogClient to read an info file created by image
creation script, add this info to the JSON response and then remove the file.

Example of new /image/create response:

{
  "disk": "1",
  "partition": "1",
  "code": "131",
  "id": "1",
  "name": "ubuntu",
  "repository": "192.168.56.10",
  "software": "Ubuntu 18.04.5 LTS \naccountsservice 0.6.45\n...",
  "clonator": "PARTCLONE",
  "compressor": "LZOP",
  "filesystem": "EXTFS",
  "datasize": 2100000
}

New fields are "clonator", "compressor", "filesystem" and "datasize".
