Answering your questions, in MOS 7.0 source code heartbeats are enabled by
default (with heartbeat_timeout_threshold value set to 60). We patched our
version of upstream stable/kilo to do so. So, in installed env heartbeats
are enabled for every component except Neutron, for which puppet manifests
explicitly disable heartbeats, as you already noted.

Regarding how should we proceed, right now we are testing how upstream
implementation performs in our environments. I suggest to postpone the
decision until we have enough data.
