Task list

Upgrade AUTH2 to Ubuntu 20.04

Hopefully last ever OS upgrade for AUTH2. So we can completely removed Quagga and BGP.

Successfully upgraded but included few snags
- PHP 5.6 ondrej package repository needed to be re-enabled and packages upgraded
- /usr/bin/php needed to be repointed from 8.2 to 5.6
- Disabled most strict modes for newly upgraded MySQL v8.0.32
- Kohana's /srv/www/default/application/classes/model/entity.php need to be manually updated to always set $this->lastModified = new \DateTime(); in save function. Otherwise Kohana tries to initially explicitly set this to NULL but should not be set so the database can do this automatically because of this config: `last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP COMMENT 'time the row was last modified',
- FreeRadius 3 config needed re-inserting /etc/freeradius/3.0/
- OpenVPN issues:
  - To be documented
- Apache issues:
  - SOWN's ca.key was too small.
  - More to be documented
Quagga was successfully removed and now only Bird2 remains which uses OSPF
