457cf49868 univention: add common code for univention corporate server modules (#16172)
* univention: add common code for univention corporate server modules

* univention: try import only univention specific libraries

* Code Review with @2-B, slight API changes and refactoring.

* Added module documentation overview, describing the provided functions
* Moved module-global objects into getter functions, so that we don't
  need to import possibly-unavailable univention modules at the module level.
* Renamed some exports for improved consistency:

  - module_name()    -> module_by_name()
  - orig_ldap        -> ldap_module()
  - ldap             -> uldap()

Note that this introduces slight API changes from the outside. Instead of
directly accessing module properties, you now have module functions with the
same name. Examples:

   - ansible.module_utils.univention.position_base_dn()
   - ansible.module_utils.univention.config_registry()
   - ansible.module_utils.univention.base_dn()
   - ansible.module_utils.univention.config()

* module_utils univention: fix library

* move module_utils from univention to univention_umc, because python import univention fails if library is called univention

* univention_umc: fix intention

* univention: change common code to BSD-2-clause

* Add OpenBSD virtualization facts.

Patch written by @jasperla.

Tested by various people on:
- virtualbox
- vmware esx(i) + fusion
- kvm (smartos + plain linux + a random cloud provider)

This patch is already present in the OpenBSD port of ansible.

* Rework diff to get rid of extra returns.

Requested by @bcoca.

While here, use four-space indentations of all code blocks.

* Set facts even if no match is found.

Discussed with @bcoca.

* Find sysctl via get_bin_path().

Requested by @bcoca.

* Fail if we do not find a sysctl binary.

* Do not fail if a sysctl binary is not found.

Just set empty fact values instead.

8fd3935029 Fix get_distribution for Alpine Linux (#17224)
To override a generic class that is subclassed based on platform, the
subclass must define platform and distribution.

The load_platform_subclass() calls the get_platform() and
get_distribution() methods to detect the platform and the distribution.

On Alpine Linux, get_distribution() method returns None and it is not
possible to have different implementations based on detected platform.

040a38171a Clean up task_executor for python3 (#17219)
ran task_executor through python-modernize and then made changes to the
code pointed out by it:

* Most places where we looped through dict.keys() changed to
      for key in dict:
  Using keys() in python2 creates a list() of keys.  For iterating, we
  can iterate over the dict itself and we'll be handed back each key.
  In python3, doing it this way does not create a new list and thus is
  more memory efficient.
* In one place, use:
      for key in list(dict.keys()):
  because we're deleting elements from the dictionary inside of the
  loop.  So we really do need to iterate over a separate list of the
  keys to avoid modifying the dictionary that we're iterating over.
  (Fixes Python3 bug)
* In one place, change the order of an if-elif-else tree so that the
  most frequent cases are evaluated first. (Optimization)

e396d5d508 Implement vault encrypted yaml variables. (#16274)
Make !vault-encrypted create a AnsibleVaultUnicode
yaml object that can be used as a regular string object.

This allows a playbook to include a encrypted vault
blob for the value of a yaml variable. A 'secret_password'
variable can have it's value encrypted instead of having
to vault encrypt an entire vars file.

Add __ENCRYPTED__ to the vault yaml types so
template.Template can treat it similar
to __UNSAFE__ flags.

vault.VaultLib api changes:
    - Split VaultLib.encrypt to encrypt and encrypt_bytestring

    - VaultLib.encrypt() previously accepted the plaintext data
      as either a byte string or a unicode string.
      Doing the right thing based on the input type would fail
      on py3 if given a arg of type 'bytes'. To simplify the
      API, vaultlib.encrypt() now assumes input plaintext is a
      py2 unicode or py3 str. It will encode to utf-8 then call
      the new encrypt_bytestring(). The new methods are less
      ambiguous.

    - moved VaultLib.is_encrypted logic to vault module scope
      and split to is_encrypted() and is_encrypted_file().

Add a test/unit/mock/yaml_helper.py
It has some helpers for testing parsing/yaml

Integration tests added as roles test_vault and test_vault_embedded

* Rm py2.7+ code in docker connection plugin

The docker connection plugin was using subprocess.check_output
which only exists in python 2.7 and later. Connection plugins
need to support python2.6 so this replaces it with Popen/communicate()

* Handle docker ver errors in docker connection

Add unit tests for DockerConnection

Fixes #16971
