First commit of instructions for deploying a simple
development sandbox using Docker.

Prevent sed from creationg a backup of bootstrap.php when
it is edited in place by the entrypoint script.

The upstream PostgreSQL image now requires that POSTGRES_PASSWORD
be set. This commit sets POSTGRES_PASSWORD to be the value
of COMANAGE_REGISTRY_POSTGRES_USER_PASSWORD if not set,
or uses the Dockerfile default of password.

Document the use of the COMANAGE_REGISTRY_NO_DATABASE_CONFIG environment
variable in the README.md file for the cron image.

Update the main README.md documentation page with a link to the
documentation for the COmanage Registry cron image.

If the environment variable OLC_ROOT_DN_PASSWORD is set but OLC_ROOT_DN
(usually a hash) is not and is set to the Dockerfile default of
'password', then take OLC_ROOT_DN from OLC_ROOT_DN_PASSWORD.

Add logic so that if the environment variable
COMANAGE_REGISTRY_NO_DATABASE_CONFIG exists then the entrypoint script
will not attempt to create the database.php file. Likewise if
COMANAGE_REGISTRY_NO_EMAIL_CONFIG exists then the entrypoint script will
not attempt to create the email.php file.

If the environment variable OLC_ROOT_DN_PASSWORD is set but OLC_ROOT_DN
(usually a hash) is not, then take OLC_ROOT_DN from
OLC_ROOT_DN_PASSWORD.

Update the base image for comanage-registry-slapd-base to use
debian:10.3.

Updated the build for the Shibboleth SP base image to use debian:buster
as the base and the appropriate development libraries for that base.

Updated the PHP version for the I2 TAP base image to version
7.3.13.

Revert mod_auth_openidc to version 2.3.11 after finding with
that environment variables for claims are not being set the same in the
2.4.x series.

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.
