End to end test CLI smoke tests

This perfroms following steps:
1. Create new organization and environment
2. Upload manifest
3. Sync a RedHat repository
4. Create content-view
5. Add repository to contet-view
6. Promote/publish content-view
7. Create an activation-key
8. Add product to activation-key
9. Create new virtualmachine
10. Pull rpm from Foreman server and install on client
11. Register client with foreman server using activation-key
12. Install rpm on client
Earlier I used this way, but later realized it's better we use.

```python
from robottelo.common import manifests
manifest = manifests.clone()
```
This way the readability is good.
