##### SUMMARY
The [__combine__ filter of Ansible](https://docs.ansible.com/ansible/latest/user_guide/playbooks_filters.html#combining-hashes-dictionaries) is limited if it comes to nested elements that contain lists. The __recursive__ functionality only does merge dict elements but not nested list elements.
* The current implementation will simply take the second list as result.
* The expected results would be to merge both lists into a single list.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
Jinjia2 integration

##### ADDITIONAL INFORMATION
Example:
```yaml
---
- hosts: localhost
  gather_facts: false
  vars:
    foo:
      list:
      - a
      - b
      dict:
        foo: 1
    bar:
      list:
      - c
      - d
      dict:
        bar: 2
  tasks:
  - debug:
      msg: '{{ {} | combine(foo, bar, recursive=True) }}'
```

Expected:
```yaml
{
  "dict": {
      "bar": 2,
      "foo": 1
  },
  "list": [
      "a",
      "b",
      "c",
      "d"
  ]
}
```
Actual:
```yaml
{
  "dict": {
      "bar": 2,
      "foo": 1
  },
  "list": [
      "c",
      "d"
  ]
}
```
