this bit should be in `~/.hammer/cli.modules/foreman.yml`, not `cli_config.yml`

```yaml
:foreman:
  :enable_module: true
  :host: 'http://localhost:3000/'
  :username: 'admin'
  :password: 'changeme'
```

`~/.hammer/cli_config.yml` should have something like what's found in the the [sample config](https://github.com/theforeman/hammer-cli/blob/master/doc/installation.md#sample-config)
