* feat(utils): make DNS resolver cache TTL configurable via RUSTFS_DNS_CACHE_TTL_SECS
The resolver cache in crates/utils/src/net.rs had a hardcoded 300s TTL with
no way to tune or disable it. On orchestrated networks (Docker Swarm,
Kubernetes) a peer's DNS name is its only durable identity while its container
IP changes on reschedule, and the platform DNS always serves the current
answer. A fixed 300s application-side cache can keep a member dialing a dead IP
for up to five minutes after a peer restarts. Rust has no runtime DNS cache, so
on musl images this was the only cache in the stack and the only one that could
not be turned off.
Read the TTL from RUSTFS_DNS_CACHE_TTL_SECS (u64, default 300), matching the
existing RUSTFS_INTERNODE_* transport knobs. `0` disables caching entirely so
every get_host_ip consults the system resolver. The resolved value is logged
once at first use, removing an invisible cache from the triage surface. Change
is backward-compatible and confined to net.rs.
Also drop the two per-lookup info! logs on the resolve path: they would flood
the log when caching is disabled and added hot-path noise otherwise.
