instance-slave-caddy-simplified-input-schema.json has been removed, as it is
not useful.

Some profiles were templates and vice versa, which was very
misleading.

The most complex case - no automatic https redirection and usage
of url and https-url is used to check implementation of type:redirect now.

3.7.3 is an "urgent" new release as announced in
https://www.postfix.org/announcements/postfix-3.7.3.html
the old 3.7.2 version seem to have bee removed from mirrors
(see http://postfix.mirrors.ovh.net/postfix-release/official/ for a
mirror with directory index) and was not in shacache.

using link-binary is enough

When using pre-commit hook (the one installed by using `npm install`
from the root of the repository), all .json files are checked to be
valid json and formatted according to the ./format-json rules.

These templates were problematic for this script because they are not
really valid json, so name them .json.jinja2 instead of .jinja2.json so
that they are not selected by the pre-commit hook

This take another approach at c5cd4e06 (component/glib: set --with-python
to generate scripts with slapos python, 2022-09-20) because this python
might exceed the limit of shebang lines, that change was bad because it
brought back the problem that we fixed in 6acdc8ca (glib: put the expected
python in $PATH, 2019-12-18)

Now that component/defaults.cfg set the ${python:location}/bin in $PATH,
we can assume that python is always in $PATH. The problem with python3
software is that python3 does not install a "python" binary, only python3,
so we can use the $PYTHON environment variable which will be set to
python2 or python3 and that in both cases this will be a valid python
interpreter.

This re-applies 7581b668 (component/glib: remove bad file bin/gtester-report
after compilation, 2020-08-07) because with this approach that script's
shebang is just #!python3

use unshare to create new user-root namesapce to have the perrmission to
create network device, use mount to update files information of network
device in /sys(nemu)
test use iptables to manage route condition, miniupnpd to manage upnp,
brctl(nemu) to create bridge, so add them in component.

add openvpn, add babel, modify ovpn-client/server

due to outdated pypi version, nemu don't include need moudle in
setup.py, so add them in buildout
