##### SUMMARY
I want to be able to use a pure (non-regex) line with lineinfile. Without accidentally escaping or not escaping characters.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
lineinfile

##### ADDITIONAL INFORMATION

I have a line in a file which has lots of special characters. I want to use Ansible's lineinfile module.

Ansible's lineinfile module requires a regular expression, which means lots of escaping for me, and a role or playbook that is more difficult to read.

Could the module support a non-regex line too?

Example of problem regex (have fun escaping this one! - real world example):

```yaml
    lineinfile:
      path: /etc/apt/apt.conf.d/50unattended-upgrades
      regexp: '#         "${distro_id}:${distro_codename}-updates";'
      line: '         "${distro_id}:${distro_codename}-updates";'
```
elif b_lines[index[1] - 1].rstrip(b'\r\n') != b_line:
                    b_lines.insert(index[1], b_line + b_linesep)
                    msg = 'line added'
                    changed = True
        elif b_lines[index[0]] != b_new_line:
            b_lines[index[0]] = b_new_line
            msg = 'line replaced'
            changed = True
    elif backrefs:
        
        
        pass
    
    elif insertbefore == 'BOF' or insertafter == 'BOF':
        b_lines.insert(0, b_line + b_linesep)
        msg = 'line added'
        changed = True
    
    
    
    elif insertafter == 'EOF' or index[1] == -1:
        
        if b_lines and not b_lines[-1][-1:] in (b'\n', b'\r'):
            b_lines.append(b_linesep)
        b_lines.append(b_line + b_linesep)
        msg = 'line added'
        changed = True
    elif insertafter and index[1] != -1:
