check.py reports duplicate image filenames

[ghost]

Currently check.py reports an error in cisco-asav.gns3a and juniper-vrr.gns3a, that they contain duplicate image filenames. After reporting this error check.py stops testing further appliances.

$ python3 check.py
=> Check appliances
Check danos.gns3a
Check arista-ceos.gns3a
.
.
Check f5-bigip.gns3a
Check cisco-asav.gns3a
Duplicate image filename asav9-16-2.qcow2
$

These duplicate images were allowed by @grossmj in https://github.com/GNS3/gns3-registry/issues/678#issuecomment-1196042244. Maybe check.py should be changed so that this condition won't stop the check.

I made two changes to check.py to allow duplicate filenames, see the enclosed patch:

• Allow duplicate filenames with different MD5 checksums as used in cisco-asav.gns3a. The change now issues a warning.
• Allow duplicate filenames with the same MD5 checksum, as used in juniper-vrr.gns3a. If you don't like that modification, remove all changes involving "md5sums".

Hi, have you closed this issue because it takes us too long to add your changes? ;)

I think that this issue is not important enough to spend time on it.
