On first install (and in tests), it may happen that the daemons
didn't manage to successfully boot by the time we attempt to
make the HTTP request to reload them, which in turn would cause
Ansible to fail.

As a short-term mitigation we skip error checking on this handler.

Tinc breaks if it finds dashes in node names, so replace them
with underscores (cf. https://www.tinc-vpn.org/pipermail/tinc/2003-January/000605.html)

Reload Prometheus components config via HTTP
