First commit of COmanage Registry Cron, intended to build a COmanage
Registry image that uses cron to execute COmanage Registry JobShell
jobs.

Updated to use version 2.4.04 of mod_auth_openidc and Debian buster as
the base.

Updated the base to PHP 7.3.13 and switched to using Debian buster.

Added the django-request-logging package to mailman-web to assist when
necessary with debugging by being able to easily log the requests
recevied by the mailman-web service.

Added the MailHeaderMiddleware to settings.py for the mailman-web
service.

Add missing - to read from stdin

Directories on host should start with /srv/docker

Fix permission on patched code

expose COMANAGE_REGISTRY_SRC_URL as a build arg

Fixed missing colon in yaml

Pin the upstream httpd image used for Mailman apache-shib to
version 2.4.38 so that he base is debian:stretch-slim.

Refactor the Shibboleth SP logging configuration so that default
shibd.logger, native.logger, and console.logger with details appropriate
for Docker images are in the base and can be easily copied into images.
Remove shibd.logger and native.logger from the COmanage Registry and
Mailman images as a result.

Updated the Shibboleth SP template configuration file to make it
consistent with the default example configuration from the
Shibboleth SP 3.0.4 release.

Removed the logger attribute from the root element
<SPConfig> of the Shibboleth SP configuration template file
so that the SP will default to using shibd.logger for out of
process (shibd) and native.logger for in proccess (module).

Updated the Mailman 3 for COmanage Registry images to
version 0.2.3 to pick up more recent version of
core (3.2.2), postorious (1.2.4), and hyperkitty (1.2.2).

Updated Dockerfiles for both COmanage Registry base and the I2 TAP base
to use PHP version 7.3.6.

Remove the shibboleth2.xml template file installed by the RPM
from the image so that it is not included when a volume is created
from the mount point /etc/shibboleth, which is declared using the
VOLUME instruction.

Added the ability to inject the relayhost configuration for postfix.

Refactored the Dockerfiles and related
tooling to leverage Docker multi-stage build
functionality. Also updated base containers
to pick up later releases of Apache HTTP Server,
PHP, Shibboleth SP, and mod_auth_openidc.

Update the Mailman 3 images and service deployment scripts so
that Apache HTTP Server with the Shibboleth SP serves as the
web proxy so that the Mailman 3 UI interfaces (Postorius and
Hyperkitty) are protected with SAML.

Changes necessary to ingegrate COmanage Registry with Mailman 3.2.0.

Fix bug when using the environment variable
COMANAGE_REGISTRY_ENABLE_PLUGIN to specify a comma separated list of
plugins to enable where the comma separated list was not parsed
correctly.

Add the ca-certificates package to the slapd base image so that any
clients or client libraries that need to call out, such as syncrepl
clients, can properly check server TLS certificates and do
ldaps://.

Update Postfix entrypoint and main.cf configuration file to enable
injection of mynetworks configuration so that the proper networks may be
enabled or restricted.

Updated Mailman 3 Web Dockerfile to pin version numbers for various
django- modules. Updated settings.py configuration to remove all
social login providers. Updated login template file to remove links
to social providers.

Removed a hardcoded server name for the Mailman nginx configuration file
and replaced with logic to inject the server name based on environment
variable.

Added a default maximum open file descriptors set with
ulimit -n for the slapd process. See
https://github.com/moby/moby/issues/8231
for a discussion of how this helps decrease the memory
used by slapd when running inside a container.

Update the source URL for santuario used by the Shibboleth SP.
