Option for custom disk description implemented

Option to add a custom disk description implemented.
Changes made in ovirt_imageio/client/_ovirt.py's
add_disk and ovirt_imageio/client/upload.py's
upload_disk to incorporate a description variable,
along with test/client_options_test.py to test
config and command line usage of the new custom
description option.

Fixes: #118
