### Configuration

```console
$ ansible-config dump --only-changed
GALAXY_SERVER_LIST(/home/jtanner/workspace/github/jctanner.redhat/ansible-hub-ui.tags/deleteme/ansible.cfg) = ['hub']
```


### OS / Environment

Fedora25

### Steps to Reproduce

```
$ cat ansible.cfg | fgrep -v token=
[galaxy]
server_list = hub
#validate_certs=false

[galaxy_server.hub]
validate_certs=False
username=jdoe 
password=redhat
auth_url=https://keycloak-ephemeral-yhd7ju.apps.c-rh-c-eph.8p0c.p1.openshiftapps.com/auth/realms/redhat-external/protocol/openid-connect/token 
url=https://front-end-aggregator-ephemeral-yhd7ju.apps.c-rh-c-eph.8p0c.p1.openshiftapps.com/api/automation-hub/ 
```

```
ansible-galaxy -vvvv collection publish foo23/test/foo23-test-1.0.0.tar.gz
```


### Expected Results

Certs should be ignored.

### Actual Results

```console
ERROR! Unknown error when attempting to call Galaxy at 'https://front-end-aggregator-ephemeral-yhd7ju.apps.c-rh-c-eph.8p0c.p1.openshiftapps.com/api/automation-hub/api': <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: Hostname mismatch, certificate is not valid for 'front-end-aggregator-ephemeral-yhd7ju.apps.c-rh-c-eph.8p0c.p1.openshiftapps.com'.
