SE-3057: Address several problems found following Vagrant install instructions.
Created by: Kelketek
- Clarified Python version requirements.
- Removed redundant instruction for HUEY_ALWAYS_EAGER environment variable, now handled by Ansible.
- Added missing instruction to perform migrations as part of initial setup.
- Added override_settings to tests which assume that AWS keys are set, which they are not by default.
@symbolist I did end up creating the above ticket since while getting my devstack up and running I found enough problems to feel like an issue should be created, but as time went on I was able to fix all of them and put them into a PR. I'm not sure if this means I should just attach it to one of my existing assigments instead, or if I should pull in the above ticket into the sprint, or, perhaps, it should be put into a future sprint with the pre-assigned status 'In Review', and assigned a reviewer later.
Please let me know your thoughts, and if there's anyone else we should have review this ticket.
