Add markdown tables to facts

[jabelk]

been meaning to do this, but putting it here as a reminder for either of us

sample data using NSO sandbox:

raw_facts:
  ansible_facts:
    ansible_net_interfaces:
      GigabitEthernet1:
        bandwidth: 1000000
        description: to port7.sandbox-backend
        duplex: Full
        ipv4:
        - address: 10.10.20.176
          subnet: '24'
        lineprotocol: up
        macaddress: 5254.0015.a879
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      GigabitEthernet2:
        bandwidth: 1000000
        description: L3 Link to core-rtr01
        duplex: Full
        ipv4:
        - address: 172.16.252.29
          subnet: '30'
        lineprotocol: up
        macaddress: 5254.0017.9819
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      GigabitEthernet3:
        bandwidth: 1000000
        description: L3 Link to core-rtr02
        duplex: Full
        ipv4:
        - address: 172.16.252.33
          subnet: '30'
        lineprotocol: up
        macaddress: 5254.000b.e9cb
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      GigabitEthernet4:
        bandwidth: 1000000
        description: L3 Link to dist-sw01
        duplex: Full
        ipv4:
        - address: 172.16.252.6
          subnet: '30'
        lineprotocol: up
        macaddress: 5254.001b.e0af
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      GigabitEthernet5:
        bandwidth: 1000000
        description: L3 Link to dist-sw02
        duplex: Full
        ipv4:
        - address: 172.16.252.14
          subnet: '30'
        lineprotocol: up
        macaddress: 5254.001c.9430
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      GigabitEthernet6:
        bandwidth: 1000000
        description: L3 Link to dist-rtr01
        duplex: Full
        ipv4:
        - address: 172.16.252.18
          subnet: '30'
        lineprotocol: up
        macaddress: 5254.0010.994b
        mediatype: Virtual
        mtu: 1500
        operstatus: up
        type: CSR vNIC
      Loopback0:
        bandwidth: 8000000
        description: to
        duplex: null
        ipv4: []
        lineprotocol: down
        macaddress: null
        mediatype: null
        mtu: 1514
        operstatus: administratively down
        type: null

| INTERFACE | DESC | PROTOCOL | STATUS |
| ------- |------ | ------- | -------|
  {% for  iname, idata  in raw_facts['ansible_facts']['ansible_net_interfaces'].items() %}
| {{ iname }} | {{ idata.description }} | {{ idata.lineprotocol }} | {{ idata.operstatus }} |
  {% endfor %}

will create a table like this

| INTERFACE | DESC | PROTOCOL | STATUS |
| ------- |------ | ------- | -------|
  | GigabitEthernet1 | to port7.sandbox-backend | up | up |
  | GigabitEthernet2 | L3 Link to core-rtr01 | up | up |
  | GigabitEthernet3 | L3 Link to core-rtr02 | up | up |
  | GigabitEthernet4 | L3 Link to dist-sw01 | up | up |
  | GigabitEthernet5 | L3 Link to dist-sw02 | up | up |
  | GigabitEthernet6 | L3 Link to dist-rtr01 | up | up |
  | Loopback0 | to | down | administratively down |

benefit of markdown tables is they render in github/gitlab nicely and can be put in pipelines for auto-documentation
