Whitespaces matter to exporter.exclude:
- patterns must *not* start with a space
- file *must* end with a newline

Also, de-duplicate paths.

When a process is stopped:
- it may not have emitted logs since previous rotation: add "missingok"
  As a direct consequence: stop using logrotate recipe.
- its pid file (if applicable) may be missing: test its non-empty presence
  before calling slapos-kill
Also, stop using slapos.cookbook:logrotate.
Update obvious users (cloudooo, neoppod, erp5, monitor, re6stnet).

Each loop in jinja2 has its own scope. This code was likely relying on a
bug, which was probably recently fixed upstream.
Using generators is cleaner as it better expresses the intent.

All parameters about SLA, i.e. computer-guid & instance-guid, are removed in
favor of a new "sla-dict" parameter, which is easier to implement and much more
versatile.

All changes in the request parameters are incompatible. The old ones are
ignored without warning/error.

For compatibility, the reference of ZEO partition is still "zodb".

Default settings were also fine. Default name of mount-point and FileStorage
file is reverted to 'root' instead of 'main'.

We now use a version of ZEO that support ipv6 natively so this is useless.

Although TIDStorage only supports ipv4, it's easier and better to fix TIDStorage
rather than maintaining such hack in SlapOS.

New 'slapos-kill' from slapos.toolbox is used instead of 'killpidfromfile'
This is required for NEO which does not write any pid file.

The inline recipe for ERP5 has been improved and converted into recipe,
which is reused for NEO.

Templates are instanciated only if they're used, so no need anymore to
wrap them with:

  {% if slap_software_type == software_type -%}
  ...
  {% endif %}

When there are many ZODBs, this command can exceed crond's maximum 1024
bytes limit.

Do not expose a parameter, as index can be reconstructed from data anyway.
Rotating is anyway needed as index backup can take a significant amount of
space for rare practical use.
Also, remove this point from TODO.

Not perfect yet, as some strings end in configuration files for example
and need escape mechanisms aware of individual configuration file syntaxes.

This follows up commit 04ff4930

This value is used as a directory name, so we should follow the common
denominator.

This work has nothing to do in erp5-component branch, and is preventing it
from being merged to erp5 banch more often.
Conflicts because of non-reverted
6d1a9805 have been resolved to that its
intent is preserved with non-cluster ERP5 SR.
