Kolla-Ansible Ceph deployment mechanism has been deprecated in Train [1].

This change removes the Ansible code and associated CI jobs.

The method `Fernet.generate_key()` generates a binary string in Python 3:
```
>>> Fernet.generate_key()
b'qSMZlOK23pZUw_Uyy-ZRPUfPskMXKGCGmhG6AHCFiV8='
```

Unless properly written as a string to the Kolla `passwords.yml` file,
the Fernet key will end up in the final Barbican config like this:
```
[simple_crypto_plugin]
kek = b'qSMZlOK23pZUw_Uyy-ZRPUfPskMXKGCGmhG6AHCFiV8='
```

Due to the fact that the key is incorrectly written to the barbican
config file (it should be written as a string), every barbican secret
store fails with:

```
barbican.api.controllers   File "/var/lib/kolla/venv/lib/python3.6/site-packages/barbican/plugin/store_crypto.py", line 83, in store_secret
barbican.api.controllers     encrypting_plugin, context.project_model)
barbican.api.controllers   File "/var/lib/kolla/venv/lib/python3.6/site-packages/barbican/plugin/store_crypto.py", line 290, in _find_or_create_kek_objects
barbican.api.controllers     kek_meta_dto = plugin_inst.bind_kek_metadata(kek_meta_dto)
barbican.api.controllers   File "/var/lib/kolla/venv/lib/python3.6/site-packages/barbican/plugin/crypto/simple_crypto.py", line 104, in bind_kek_metadata
barbican.api.controllers     encryptor = fernet.Fernet(self.master_kek)
barbican.api.controllers   File "/var/lib/kolla/venv/lib/python3.6/site-packages/cryptography/fernet.py", line 38, in __init__
barbican.api.controllers     "Fernet key must be 32 url-safe base64-encoded bytes."
barbican.api.controllers ValueError: Fernet key must be 32 url-safe base64-encoded bytes.
```

This commit fixes the issue described above by properly writing
the Fernet key as a string to the Kolla `passwords.yml` file.

When methods for passwords generation and merge are
extracted then external apps and scripts can use
those methods without resolving to subprocess execution
or injecting sys.argv.

Sha password is not always valid for barbican cripto key.
Use a fernet key so it always gets valid.

Not need release note for upgrade, users with a working
barbican not regenerate passwords, only new passwords will
get new type.

Due to the changes in hmac.new and how binary strings
are dumped in yaml.safe_dump some changes were needed to
make sure that we dumped only strings, not binary strings.

now.
