Use submission port for client outgoing email

Eliminate need for access_compat module in Apache

Remove duplicate when statement in Let's Encrypt task

While adding the Let's Encrypt offline testing block in 1746afcc we
accidentially duplicated a the 'when' statement. Ansible only looks at
the last when statement for a given block meaning the earlier one has no
use. This commit merges both lines in one.

Update testing to work with modularized Sovereign

* Harvest testing configuration into group variables
* Define testing group for Vagrant to use
* Move testing passwords to secrets directory that Vagrant uses
* Update .gitignore to keep the testing secrets

VPN - enforce TLS min version on the client

The directives provided by `mod_access_compat` are deprecated.  This
patch eliminates references to them.

Currently client email is submitted via ssmtp (port 465).  This has been
deprecated for years.  The correct way to submit email is via
submission (port 587).

This patch adds port 587 as a second and the default way of submitting
email for delivery.  Port 465 remains open for backwards compatibility
with existing clients.

functionality to be located in Sovereign.
