'version' is not a valid attribute

[andrestc]

I'm getting the following error while trying to run this role inside a playbook in ansible 2.2:

ERROR! 'version' is not a valid attribute for a RoleMetadata

The error appears to have been in '/usr/local/etc/ansible/roles/aalda.docker-registry/meta/main.yml': line 2, column 1, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

---
galaxy_info:
^ here

Seems that this metadata is not support anymore: ansible/ansible#13496
