OpenVPN fails to build on Debian testing because
net-tools is no longer provided by default.
Depends on nexedi/slapos@67eb9fe4

Commit c5e509c3
added the ability to download from network cache when building re6st,
but slapos.libnetworkcache is imported after bin/buildout has
already been generated. The fixup consists of adding libnetworkcache
in bin/buildout from bin/python, which has been renamed to
bin/python.temp until the end of bootstrap to start again if we fail
before the end of the task.

apt package didn't support direct list input for "name" arg. Use
with_items instead.

the IMT settings already contains slapos master urls

This reverts commit 8fdf3f1a.

It's all the more important as OpenVPN tarballs can't be downloaded with
default Python user-agent.

`slapos.libnetworkcache` depends itself on `setuptools`.

INSTALL_PREFIX has been deprecated in openssl so it was renamed to DESTDIR and uses the
new `make-install-extra` option added here:  nexedi/slapos!524

Useful for unstable connection to some (distant) servers, also the package is available on chromebrew too.

PS: The package seems also to be available in almost all Linux distributions: https://pkgs.org/download/mosh

this is needed for all servers hosting VMs. As we don't really know which server are hosting VM, we do it on all vifib servers.

This will be useful to setup machines where we already have IPv6 (for example, VM with IPv6 coming from the host).

As slapos is started by cron, this number will reach the default limit very fast
