Use 2 different ports on apache for cached slaves, to differ http and https accesses.
  Introduce the parameter https-url (with fallback to url) to include specific https urls,
    if they are different from url.
  Include /HTTPS/ mapping to traffic server to differ the backends based on the input.

  Not all frontend clusers setup uses the same re6stnet network.

Anyway, the repository contains more than just rina-tools.

  If pidfile is empty, the pgrep will fail forever until the pidfile
  is removed, so check if it exist and it is not empty.

  The promise returns too much data into the PIPE, if it is the case, it makes
  the promise much much slower, causing constant timeout

This is implement as a test suite so that it can be automatically on any commit
to rina/slapos repositories.

Currently, the Debian packaging of the kernel only supports Debian Jessie.

Because slapos.core hardcodes a "supervisord.socket", this file happens to be deleted and cause bugs

This solution is better than adding a sleep in a crontab, because it will be a new
date every day

Revert "resilient: new paramater to define the time to sleep before running the backup in the cron job."

This reverts commit 30d1a937.

It includes more debugging lines, not deploying a slapproxy (no need anymore thanks
the free-port selection recipe), and not delegating some work to a cron job.

In gunicorn v19.6 and v19.5, a bug was introduced which deletes socket when nginx worker exits.
In our case, it crashes the slaprunner and prevents it from restarting by slapos.
Let's stick to v19.4.5 until this issue is closed : https://github.com/benoitc/gunicorn/issues/1298

Default is a random value between 0 and 6 hours. KVM and Slaprunner test instances set it at 0.
