Better integration with AppDB

Possible integration points: use images from AppDB instead of the local names / ids

[tdviet]

Openstack commands accepts only local names/IDs, however, that can be easily retrieved using appliance title or other properties (appliance IDs, MPURI, ...) in AppDB, for example:

fedcloud openstack image list --property "dc:title"="Image for EGI Docker [Ubuntu/18.04/VirtualBox]" --site CESNET-MCC  --vo eosc-synergy.eu -c ID -f value
a0f85909-e117-4463-bea7-78ed06d160e3

We can add some new parameters for better integration with AppDB, e.g. "--appliance-title TITLE", and internally converting the parameter to "--image local-id". However, there are several issues:

• Some sites have duplicated images (like CESNET_MCC above, two images with the same title)
• Some sites have images without properties (like IFCA-LCG2)

Until that is clarified, it would be better to do the conversion in external script that is easier to debug.

BTW, why several properties are duplicated, e.g. "APPLIANCE_TITLE" and "dc:title" properties, they have the same value.
