##### SUMMARY
<!--- Describe the new feature/improvement briefly below -->
The ios_banner currently strips any text passed to it, making certain banner formats impossible to replicate properly.

##### ISSUE TYPE
- Feature Idea

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

##### ADDITIONAL INFORMATION
<!--- Describe how the feature would be used, why it is needed and what it would solve -->
Add a boolean switch to the module params (`strip`, perhaps) that would conditionally strip or not the text passed from the param. Could be optional and default to `True`.

<!--- Paste example playbooks or commands between quotes below -->
```yaml
ios_banner:
  strip: no
  banner: login
  present: yes
  text: "{{ lookup('template', 'banner.j2') }}"
```
with the `banner.j2` looking like
```
