Removes hardcoded 10.40.40.202 references so a fresh clone + .env-only
edit can stand the stack up on a new compute node.
* docker-compose.yml: rib-poller PG_DSN now uses ${HOST_IP:-...}.
* obmp-rib-poller/poller.py: default PG_DSN host falls back to
${HOST_IP} env (compose passes it; manual runs honour $HOST_IP too).
* cml/gobgp_peering_config.py: GOBGP_IP read from $HOST_IP or the
HOST_IP= line in repo-root .env, with a small _env_default helper.
* cml/proxmox_bmp_config.py: COLLECTOR_HOST resolved the same way.
For gobgp/gobgpd.conf and gobgp-evpn/gobgpd.conf -- jauderho/gobgp is
distroless (no shell), so we can't sed-substitute at container start.
Pattern instead:
* gobgpd.conf is now gobgpd.conf.tmpl with __HOST_IP__ placeholders
(committed). The rendered gobgpd.conf is gitignored.
* setup.sh renders the .tmpl(s) to .conf using $HOST_IP from .env.
* compose `command` stays the simple `gobgpd -f /config/gobgpd.conf`.
After cloning on a new host: cp .env.example .env -> edit HOST_IP ->
./setup.sh -> docker compose up -d. Verified locally by force-recreating
gobgp; all 6 sessions (4 cores + 2 Bromirski) re-established in <60s.
Known portability gaps still to address (separate work):
* Hardcoded lab-router inventories in cml/*.py and
obmp-rib-poller/poller.py.
* The /etc/cron.d/openbmp */5 -> */15 edit inside obmp-psql-app is
not persistent (regenerated by config_cron on every container start).
