Use slapos.recipe.template instead of slapos.recipe.template if possible

Harmonize template keys :
rendered -> output
template -> url
template = inline: -> inline =

Delete "mode" key

See merge request nexedi/slapos!1151

Adapt all promise sections to changes in plugin promise recipe.

Change all `check_port_listening` promises to `check_socket_listening`
and rename all associated `config-hostname` arguments to `config-host`

As possible cover promises in tests.

We'll add monitoring to NEO so some parts are also moved there from ERP5.

whenever the zope instances have the same title (example all zope have 'Zope monitor' as title) the request to frontends consider it as the same request and gives same frontend to each of them.

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).

This was broken since commit 690be0d0
("Merge branch 'master' into erp5-cluster").

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 %}

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.
