##### SUMMARY
`ansible-galaxy import` is broken, potentially by the introduction of the `collection` subcommand? Fails early trying to read CLI args...

##### ISSUE TYPE
- Bug Report

##### COMPONENT NAME
`ansible-galaxy`

##### ANSIBLE VERSION
```
ansible 2.9.0.dev0
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/home/calvin/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /home/calvin/projects/ansible/lib/ansible
  executable location = /home/calvin/.local/share/virtualenvs/orion/bin/ansible
  python version = 3.6.8 (default, Mar 21 2019, 10:08:12) [GCC 8.3.1 20190223 (Red Hat 8.3.1-2)]

```

##### CONFIGURATION
<!--- Paste verbatim output from "ansible-config dump --only-changed" between quotes -->
```
(empty)
```

##### OS / ENVIRONMENT
<!--- Provide all relevant information below, e.g. target OS versions, network device firmware, etc. -->


##### STEPS TO REPRODUCE
Simply invoke the `import` subcommand or any repository:

```ansible-galaxy import -vvv --server=http://127.0.0.1:8000 orionuser1 ansible-testing-content```

<!--- HINT: You can paste gist.github.com links for larger files -->

##### EXPECTED RESULTS
<!--- Describe what you expected to happen when running the steps above -->
An import to start, to observe the import log, and be given the results.

##### ACTUAL RESULTS
<!--- Describe what actually happened. If possible run with extra verbosity (-vvvv) -->

<!--- Paste verbatim command output between quotes -->
