    - name: trunk allowed vlan
      pattern_match:
        regex: "  switchport trunk allowed vlan (.*)"
        content: "{{ item }}"
        match_all: yes
      register: allowed_vlans


Return would be somewhat like
```
"allowed_vlans": [
                    {
                        "matches": "15-19,25-29,35-39,45-49,55-59,65-69"
                    }, 
                    {
                        "matches": "add 85-89,95-99,636,698,752,901,997"
                    }, 
                    {
                        "matches": "add 1104,1119,1999,3800-3810"
                    }
                ],
```
