[joshuarli]

this says Container kafka did not become healthy within 120 seconds. but kafka ended up being healthy right after - not sure why but let's increase the default timeout to 180s

also while we're here - let's add per-dependency timeouts

---

Adds per-dependency healthcheck_timeout configuration to devservices by
moving the timeout field from ServiceConfig down to Dependency, threading
it through a new ContainerHealthcheckConfig type (replacing
ContainerNames) so each container's wait_for_healthy call uses its own
configured value. Each dependency now prints its timeout when waiting
(Waiting for kafka to be healthy (timeout: 300s)). Defaults to 180s (up
from 120s). Known limitation tracked in TODO.md: remote sub-service
containers (e.g. kafka inside snuba) cannot yet be individually configured
from the calling service's config.
