Adjust `self._cleanup` to new signature from nexedi/slapos.core!156

Now that component/glib/buildout.cfg is no longer included by pkgconfig,
qemu no longer build with:

    While:
	Installing.
	Getting section template.
	Initializing section template.
	Getting section template-nbd.
	Initializing section template-nbd.
	Getting section kvm.
	Initializing section kvm.
	Getting option kvm:configure-options.
	Getting section glib.
	Error: The referenced section, 'glib', was not defined.

Also explictly add pcre to prevent same problem later.

The OS may not have Python (slapos-node package does not depend
on any version of Python). Another possible issue was found on Suse:

  make[3]: Entering directory '.../parts/glib__compile__/glib-2.56.4/gio'
    GEN      gdbus-daemon-generated.c
  Traceback (most recent call last):

Building normal glib is a nightmare, at least as long as we
haven't stopped using Python 2, so let's try to avoid it.

This makes bin/pkg-config bigger (GCC 6.3.0):
 old size:  47880
 new size: 573992

With Link Time Optimization, GCC 8.3.0 produces a binary of 154656 bytes.
However, GCC 6.3.0 fails to link so we have to wait.

Improvements in check_surykatka_promise:

 * SSL certificate checked for expiration (15 days before expiration)
 * messages from the promise are more readable

/reviewed-on nexedi/slapos!675

Supports SSL checks in check_surykatka_json.

This version exposes ssl_certificate information for hosts.

Caddy by itself does not raise soft limit of open files, so it has to be set
by the wrapper.

As slapos.cookbook:wrapper can't be used for such case, the
slapos.recipe.template:jinja2 recipe inline style is used to have full
control over the created wrapper.

Version 3.0.0 requires requests>=2.22.0

Errors were raised in ERP5 with classes inheriting from ExtensionClass.

This promise check if nextcloud app was correctly deployed, it ensure that slapos instance will deploy until nextcloud install succeed.

The called python program is python3 program, and provided
PYTHONPATH is from python2, resulting in bad behaviour.

On testnodes, python can be too long for linux shebang (#!) line.

We had for example:
    
    /srv/slapgrid/slappart15/srv/testnode/cqc/inst/test0-0/tmp/shared/python2.7/338ccc0e387d64185920266f8a97c87b/bin/python2.7
  

that is 123 characters long.

With this, the generated glib-genmarshall script will have:
    
    #!/usr/bin/env  /srv/slapgrid/slappart15/srv/testnode/cqc/inst/test0-0/tmp/shared/python2.7/338ccc0e387d64185920266f8a97c87b/bin/python2.7

which exceeds the linux kernel limit.

Instead, we generate scripts that will use
    
    #!/usr/bin/env python

and it will be the caller responsibility to set $PATH to use the expected python.


This fixes the issues we had on SlapOS.SoftwareReleases.IntegrationTest tests since we updated glib to 2.56.4 in a7a86db9

Provides a way to monitor edge PoP by using surykatka tool with
monitoring promises added in slapos.toolbox 1.101

Adds edgetest and edgebot software types, where edgetest is a software type
to request by user and requests by itself edgebot, which does the monitoring
work.

- make profiles for software-types "self contained"
- add default ports ( because port is marked required )

installing vscode-ripgrep creates a folder in temporary directory, but
never removes it.

On our test nodes it was observed that a first testnode running installs
and create this folder in /tmp/ then another testnode running as another
unix user installs and we had this error:
