Add support for converting disks

[spameier]

SUMMARY

The module ovirt_disk should be extended to support the conversion of disk from raw to qcow2 or vice-versa. This is possible in the latest oVirt version according to the API docs.

COMPONENT NAME

ovirt_disk

ADDITIONAL INFORMATION

The parameter format is already present but is only used when uploading files AFAIK. If this parameter is provided the module should check the format of the disk and if it's not in the desired format convert it by issuing a call to convert.
