no reason to have an exception here.

CPU temperature promise will now come from monitor SR

See https://firewalld.org/documentation/configuration/firewalld-conf.html#ipv6_rpfilter

When re6st is running with tunnels, the IPv6 packets can come in through
an interface and go out through another. This is expected.

also use same version as stack/slapos.cfg for other eggs.

The official version of manuel has now the fix for which we needed a dev
version.

Pick the latest python2 compatible version.

Rotate every 100MB over enb.xlog, enb.xlog.1, ... enb.xlog.9

Add a service that runs `xamari xlog stats[samples,rf]/<period>s` in
enb/gnb instance. For now the resulting logfile enb.xlog/gnb.xlog is
placed in monitor public folder to be served by monitor http server.

Optionally the service also includes `x.drb_stats/<period>s`, which
implies 100Hz polling. This is enabled by default.

Marking that publish failed is important, but allow the operator of the system
understand what is the real problem (aka - do not swallow exception
information) is also very important.

In nexedi/slapos@0cf70a6e we already migrated the NEO URI concatenation to the
recent format used by WCFS. Unfortunately we missed separating the address
(IPv6 + port) of the master nodes from each other. Without adding the
separator ',' between them, WCFS doesn't work with NEO clusters which have
multiple master nodes, because NEO/go can't split the different master node
addresses.
