The password is anyway present in the section itself, so it's eventual change
will result with reinstalling the section.

This way buildout can reuse egg caches and it's a bit faster:

To run a simple instance buildout, from 2.837s it goes down to 1.875s.
To run slapos node instance 10 times just after requesting an ERP5 instance, it goes from ~112s to 98s

Changes configuration files to run repman tests in python3.

Adds the newly added to nexedi's repositories rubygemsrecipe (https://lab.nexedi.com/nexedi/rubygemsrecipe) to the list of tested eggs.

This also fixes rpath of rust binaries.

When proftpd software release is tested locally, the socket named /srv/slapgrid/slappart76/srv/runner/instance/slappart1/tmp/soft/91d420e3970a2088e648d2eb86e155ea/parts/prof is created but never removed.
First it is not an appropriated directory to create a socket and then not removing this socket leads to an error if tests are run a second time :

subprocess.CalledProcessError: Command '('ldd', '/srv/slapgrid/slappart76/srv/runner/instance/sla
ppart1/tmp/soft/91d420e3970a2088e648d2eb86e155ea/parts/prof')' returned non-zero exit status 1.

This is due to code in https://github.com/proftpd/proftpd/blob/master/src/ctrls.c :

We don't plan using varnish like this.

stop-on-error during instantiation can lead to endless instantiation in some
cases, which disallows to create services required for given part to pass, and
in the same time in many cases the called scripts are smart enough to continue
and restart on error.

Thanks to this, it's much easier to find relevant configuration, and also logs
are becoming much more informative.

Avoid creating needless entries and minimise needless newlines, and reflect
this in test data, as in such case no backend_log is created, as nothing is
configured on backend Haproxy level.

SSL cache is unusable in context of caddy, same for the so called HTTPD home.
Those are old Apache leftovers.

It's a dict, and in SlapOS usage of Jinja2 it's good to see the type of
a variable immediately.

"parameter_dict" says nothing, whereas "software_parameter_dict" explains
source and purpose of the information.

There is needless duplication of information.

That's true, that those are templates, but the important information which
shall be in the name of the parameter is its purpose - a profile.

Section template-apache-frontend was not updated in buildout.hash.cfg

development.cfg is never used, and having split software definition in
software.cfg and common.cfg just makes development harder.

This reverts commit 1c2d1c0a.
because NEO is not ready for such change.

nbd-host and nbd-port is not required in case of simplified configuration, use
boot-image-url-select instead.
