##### SUMMARY
<!--- Describe the new feature/improvement briefly below -->
When installing or updating an already held apt package with the `apt` module, it fails. 
This forces to use the `force: yes` option that it's too broad and already deprecated by apt.

Add an option `allow_change_held_packages` to the `apt` module to use the `--allow-change-held-packages` `apt` option.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
<!--- Write the short name of the module, plugin, task or feature below, use your best guess if unsure -->
apt

##### ADDITIONAL INFORMATION
<!--- Describe how the feature would be used, why it is needed and what it would solve -->


<!--- Paste example playbooks or commands between quotes below -->
```yaml
- name: Install package with specific version and hold
  block:
    - name: Install {{ package_name }} version {{ version }}"
      apt:
        name: "{{ package_name }}={{ version }}"
        state: present
        (force|allow_change_held_packages): yes

    - name: Hold {{ package_name }} package
      dpkg_selections:
        name: "{{ package_name }}"
        selection: hold
```

This is not idempotent without the `force: yes`, the second run will fail. 
The `allow_change_held_packages` will avoid problems with this special situation.
