RCA: the exabgp container was OOM-killed — its 512m mem_limit was far too
small for the full-table feature (900K route objects in memory). Raises the
limit to a parameterized 6g default (EXABGP_MEM_LIMIT).
Adds Docker healthchecks to 14 services (port/HTTP probes) so unhealthy
containers are visible. Adds a Telegraf docker input that collects per-
container CPU/memory/IO into InfluxDB, plus a "Stack Resources" dashboard —
so resource pressure is caught before it causes an OOM crash. telegraf runs
with an overridden entrypoint so it keeps root and can read the docker socket.
