This is refactoring the PoC for deploying cgit on pve, to now move to a
more standard deployment with dedicated agnonstic proxy role/container

The ansible-distro-install depends on using chroot as the connection
`Failed to connect to the host via ssh: ssh: Could not resolve hostname /mnt: Name or service not known`
moving the ansible_connection variable into the all group, overrides the
connection automatically created for the inventory in the
ansible-distro-install repo, causing the configure playbook to fail

This reverts this change and define the connection on the inventory
level
