Garage RPC connections have no TCP keepalive enabled. When a connection dies silently (proxy pod restart, NAT timeout, network partition), it's only detected by application-level pings after ~60s (4 failed pings x 15s interval). During this window, the node appears connected but all RPC calls to it fail.
Enable TCP keepalive on both outgoing and incoming RPC connections via socket2:
- Idle time before first probe: 30s (TCP_KEEPALIVE_TIME)
- Probe interval after first: 10s (TCP_KEEPALIVE_INTERVAL)
A helper set_keepalive() function avoids duplicating the socket2 setup. Incoming connection keepalive failures are logged as warnings but don't reject the connection.
Companion to #1345 (stale address pruning + connect timeout). Together they address both halves of the reconnection problem: faster detection (this PR) and faster recovery.
