Missing update from previous commits

branch 1.0 is pinning the following repositories:
 * erp5
 * vifib
 * wendelin
 * wendelin.core
 * neoppod-repository

For resiliency, it's better to pin the repositories (we want exactly the
same software on runner0 and runner1). If people wants to develop inside
one of those repositories, they will clone it inside srv/runner/project
directory and this will be sync on runner1.

Rename was missing in buildout.hash.cfg

In "caddy-frontend: Implement KeDiFa SSL information" the certificates were
dropped from the schema, but still internally supported. This lead to missing
UI fields for still supported parameters.

Reintroduced them with OBSOLETE mark.

nginx-push-stream-module still it prevents from compiling nginx.

It is ready when all on-watch processes are not EXITED.

This reverts commit 83e9bd45

"openssl ca" is keeping track of all generated certificates in its DB.
If we try to regenerate a certificate that was already generated,
openssl ca fails with :

ERROR:There is already a certificate for /C=XX/ST=(State,)/O=Company/CN=ca-shellinabox/emailAddress=xx@example.com

Changing "unique_subject" to no removes this ERROR.

Before normalize_ae_gzip was 0, and better keep it this way as it is
suspected root problem of incorrectly varianted cache depending on
client Accept-Encoding.

This reverts commit 8251f3dd.

1.4.23 is not available on pypi yet, causing all involved software releases
to fail instanciating, breaking all tests.
Feel free to reapply once the version is actually released.

Since we moved to MariaDB 10.3, that's actually already the case
because of --plugin-maturity=gamma

mock is only a test dependency for zobduri

https://github.com/getsentry/responses A utility for mocking out the
Python Requests library.

https://docs.python.org/3/library/unittest.mock.html

Instead of expensive and long checking of the configuration during promise run
read last stored state.

This decouples configuration validation calculation from promise check. The
validation information is updated often (on each configuration change, on each
reload, etc) and every 2 hours.

Validation happens on each configuration change, but for sure it is checked
each 2 hours.

State of configuration is calculated in separate script.

Order of files does not matter for the assertion.

Tests need to open xz files for checking.

It's interesting what appears in cron entries, as they are important for proper
partition usage.

Always work from the slave_dir path for extensibility and allow no ignore
paths if caller does not need to ignore anything.

Ignore path's shall be relative to checked directory.

Move files from var/log/trafficserver/*old to
srv/backup/logrotate/trafficserver, xz them and clean files older than a
year.

As some tools are not configurable with logrotate provide a script to
"rotate" files generated by those tools.
This script more or less follows logrotate behaviour:

 * moves rotated files to logrotate directory
 * compresses them with xz
 * have to be configured to keep only files for some days

Roll logs each 24h, as it would be expected.

  Upper limits makes harder deploy larger systems

Stderr to null redirection happened in the wrong place.
