VMware: New module vmware_host_dns (#64458)

Browse Source 
* Restore module vmware_dns_config
* Remove domainname and change_hostname_to
* Changed version_added from 2.10 to '2.10'
* Add setup_attach_host: true to test case
* Add 'vcsim is not defined' block to integration tests
* Change 'result' to 'dns_config_result'
* Bugfix: Changing some static configurations while keeping others can crash the module
* Implement changing DNS config from DHCP to static on a cluster
* Update documentation for vmware_host_dns
* vmware_host_dns integration tests: Always revert to original DNS configuration, even if a test fails
* Deprecate vmware_dns_config

* The :ref:`docker_container <docker_container_module>` module has a new option, ``container_default_behavior``, whose default value will change from ``compatibility`` to ``no_defaults``. Set to an explicit value to avoid deprecation warnings.
The following modules will be removed in Ansible 2.14. Please update your playbooks accordingly.
* ``vmware_dns_config`` use :ref:`vmware_host_dns <vmware_host_dns_module>` instead.
