Improve ARM support - remove explicit arch deb options

Digitalocean has proven to be an unreliable mirror so let's switch to
another one (from the official MariaDB site).

Change MariaDB mirror source

Enabling pipelining for SSH connections only means that `become` behaves differently for vagrant, than it does VMs over SSH. Moving this config to the defaults makes both vagrant and VMs behave the same in regards to become, and perhaps we will see some local speed improvements on local provisions as a result.

chore(github): fix typos in issue templates

This was needed to prevent Logjam attacks but those only applied to DHE
cyphers which haven't been supported in Trellis for 2 years.

Remove ssl_dhparam and Diffie-Hellman group

Remove issue closer

Bump vagrant_ansible_version to 2.10.7

2.2.19 has a bug affecting macOS Big Sur and should be avoided.

Require Vagrant < 2.2.19

Ubuntu 22.04 no longer supports UDP for NFS. UDP might offer better
performance on 20.04 and older boxes so it can be re-enabled manually.

And while there's no plans to switch to NFS v4, it doesn't support UDP
either.

`ansible_user` can't be assumed to be defined during Ansible local
provisioning (the default mode in Vagrant if Ansible is not installed on
the host machine).

Fixes "invalid or malformed argument" issue

Fix doc link in "Deploy WP site"-step message. URL should be redirected IMO additionally.

Gives the ability for users who have the libvirt plugin installed on linux to use libvirt/kvm for creating the virtual machine. This change will make sure that the RAM and CPU count will be properly set on each trellis up.

* Change vmname to title for libvirt vagrant provider
* Added KVM Acceleration to the VM.

In order for a more accelerated virtual machine, KVM needs to be installed and set as the driver, so that the VM will be a lot faster.

This might also help others in the future.

Trellis CLI is now preferring `trellis.cli.yml` as the main config file path
over `.trellis/cli.yml` (though it remains supported).

This now makes it possible to gitignore the entire `.trellis` directory
as it contains CLI generated files for machine use only.

`.trellis/cli.yml` is exempted in the gitignore for legacy compatibility
purposes.

Allows customization of the PHP-FPM service configuration. Previously
only the _pool_ configuration was exposed in Trellis. This allows for
more advanced performance tuning.

The PHP-FPM php.ini template is the default values as a starting point.
