Since [1] some timings seem to have changed. This caused the unit tests
to fail intermittently, from my testings especially on Ubuntu systems
(much less often on e.g. Arch).
This commit adds the `dockergen_wait_for_event` helper-function to try
and wait for the configuration to be generated by docker-gen before
continuing on with the actual tests themselves.
Additionally, at the end of every test file, all containers spun up by
the bats-tests will be stopped. This required adding the `bats-type`
label to every container started during the bats-tests.
The stopping of the containers reduces the amount of events docker-gen
has to process, thus resulting in lower wait times for the generation to
happen.

current base image does not have commented configurations which means is impossible to use the previous configuration to set the server name max length
This changes the base-image to the official nginx image,
reducing the virtual size of the image by approx 50%.

This adds SSL support for containers. It supports single host
certificates, wildcards and SNI using naming conventions for
certificates or optionally specify a cert name (for SNI). The SSL
cipher configuration is based on mozilla intermediate profile which
should provide compatibility with clients back to Firefox 1, Chrome 1,
IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7. The
configuration also enables OCSP stapling, HSTS, and ssl session caches.
To enable SSL, nginx-proxy should be started w/ -p 443:443 and -v
/path/to/certs:/etc/nginx/certs. Certificates must be named:
<virtualhost>.crt and <virtualhost>.key where <virtualhost> matches
the a value of VIRTUAL_HOST on a container.
For wildcard certificates, the certificate and private key should be
named after the wildcard domain with .crt and .key suffixes. For example,
*.example.com should be name example.com.crt and example.com.key.
For SNI where a certificate may be used for multiple domain names, the
container can specify a CERT_NAME env var that corresponds to the base
file name of the certificate and key. For example, if you have a cert
allowing *.example.com and *.bar.com, it can be name shared.crt and
shared.key. A container can use that cert by having CERT_NAME=shared and
VIRTUAL_HOST=foo.example.com. The name "shared" is arbitrary and can
be whatever makes sense.
The behavior for the proxy when port 80 and 443 is defined is as
follows:
* If a container has a usable cert, port 80 will redirect to
443 for that container to always prefer HTTPS when available.
* If the container does not have a usable cert 503 will be returned.
In the last case, a self-signed or generic cert can be defined as
"default.crt" and "default.key" which will allow a client browser to
at least make a SSL connection.
