All generated secrets are now correctly encoded.

Fixes issue #61.

Ports in public_tcp_endpoints should be opened up in the net-overlay
firewall configuration, not in the generic one ("allow-cluster" is a
misleading target, it only involves public IPs).

base: open public_tcp_endpoints

Provide a run-parts reload directory for services to put their
custom reload scripts in. Replaces the previous hard-coded reload
of nginx, which isn't appropriate on non-frontend hosts.

public-ssl-cert: change permissions only on file creation

# Conflicts:

We were using all hosts with shard_ids for all domains, regardless
of the scheduling_group, so some certificates would fail validation
due to nonexisting domains.

10GB is the default, and docker images alone are 7GB.

prometheus: alertmanager email flag

Include port in float upstream name

test: use vagrant libvirt provider as needed

Also fix some phrasing here and there.

Allow for the same name to run on different ports, e.g. when service
endpoints are "mounted" onto distinct frontend url paths.

Simplify the Ansible side of Docker container setup, as we don't have
to look up the user and group via Ansible modules (that fail in
check mode because we weren't doing it right anyway)...

Now you can install the same service credentials for multiple services
(preferably not on the same host, that's still gonna result in at least
one service using the wrong certificate). This might be legitimate for
dependent services that need some of the float functionality (like x509)
without being actually modeled at the services.yml level. An example
would be replds@acme.

Also fix the x509_csr module to no longer depend on magic 'float'
variables but accept instead its parameters as arguments. And fix
the Docker templates to account for multiple credentials with different
names.
