### Summary

I would like to configure several Galaxy servers with a fallback precedence defined by the `ANSIBLE_GALAXY_SERVER_LIST` environment variable...

https://docs.ansible.com/ansible/latest/reference_appendices/config.html#galaxy-server-list

and I would like to have 1 of those severs set to not verify SSL.

So say that I `export ANSIBLE_GALAXY_SERVER_LIST=A,B`, then I would like to `export ANSIBLE_GALAXY_SERVER_B_VERIFY_SSL=false`, and leave it true for server A.

### Issue Type

Feature Idea

### Component Name

lib/ansible/cli/galaxy.py

### Additional Information

Followup from AWX issue https://github.com/ansible/tower/issues/5182

Right now we have a global setting to turn off Galaxy SSL verification, however, it is argued that this is impractical from a security standpoint, and if someone wanted to bypass the rules, they would like to do it specific to one specific server they have added a credential for.
