This commit fix "List Native Roles" task with Elasticsearch 7.11.0+
by removing the unused `body_format` parameter from `uri` module.
This parameter isn't used with a GET method but make request fail with
`request [GET /_security/role] does not support having a body` error
with Elasticsearch 7.11.0+.
This commit is removing the option to install Elasticsearch OSS
distribution for version >= 7.11.0.
This is due to Elasticsearch recent license change.
See https://www.elastic.co/blog/licensing-change for more details.
- Add notice to breaking changes and update documentation
- Fail the deployment if trying to install OSS >= 7.11.0
- Remove OSS tests for 7.x except the upgrade test from last OSS version
to default distribution
Without become option stat operation for old users file will work only if user is in elasticsearch group, but copying of old file will fail because user have no write access in elasticsearch config dir.
- rename es_enable_xpack variable to oss_version
this variable name should be more explicit and consistent with the xpack changes made in 6.3
es_enable_xpack can still be used but is deprecated and will be removed in a later version.
- remove es_xpack-features variables
this variable was not working anymore since 6.3 [0]

From Ansible doc (https://docs.ansible.com/ansible/latest/modules/template_module.html#template-module)
For those used to /usr/bin/chmod remember that modes are actually octal numbers. You must either add a leading zero so that Ansible's YAML parser knows it is an octal number (like 0644 or 01777) or quote it (like '644' or '1777') so Ansible receives a string and can do its own conversion from string into number.
Giving Ansible a number without following one of these rules will end up with a decimal number which will have unexpected results.
The log4j configuration template provided by this ansible role doesn't reflect current log4j configuration in elasticsearch 6.x and 7.x.
Also this template doesn't contain any variable so everything is hardcoded inside.
As we don't need to override any value inside, let's use standard elasticsearch log4j configuration file provided by elasticsearch package and stop overriding it with this role.
