`maven_artifact` uses httplib2 that attempts anonymous access even if user/password is provided.

So access log looks like:

```
/opt/bitnami/apps/artifactory/artifactory_home/logs/request.log:

20191108102644|3|REQUEST|188.163.xxx.xxx|non_authenticated_user|GET|/libs-snapshot-local/xxx/2.14.0-SNAPSHOT/maven-metadata.xml|HTTP/1.1|401|0
20191108102644|2|REQUEST|188.163.xxx.xxx|reader|GET|/libs-snapshot-local/xxx/2.14.0-SNAPSHOT/maven-metadata.xml|HTTP/1.1|200|792
```

Our repository Artifactory blocks access (per IP??) if too many 401 happens.

Ansible then fails with:

```
failed: [stage-server] (item={'name': 'tp-sc', 'jmx_port': 18004}) => {"ansible_loop_var": "item", "changed": false,
  "msg": "Failed to connect to example.com at port 443: [Errno 110] Connection timed out",
  "status": -1,
  "url": "https://example.com/artifactory/libs-snapshot-local/xxx/2.14.0-SNAPSHOT/server-2.14.0-20191108.084713-5.jar.md5"}
```

There is a patch that fixes the behavior of httplib2 : https://github.com/DorianGeraut/maven_artifact_work/commit/5fff2870ba1e8dee864b21eb3a2ea40c10547484
