feat: ssh-console use ASF Presence Ping for IPMI check

Is this a new feature, an enhancement, or a change to existing functionality?

Enhancement

How would you describe the priority of this feature request

Medium

Please provide a clear description of problem this feature solves

ssh-console uses icmp ping to check if an IPMI endpoint is reachable before attempting to connect. This is unreliable because:

1. Kubernetes Service ClusterIPs don't respond to ICMP ping. We use ClusterIPs with Machine-a-tron simulations.
2. Network acls, firewalls may block icmp traffic while allowing IPMI udp.

Current behavior:

• ssh-console spawns ping -c 1 -W 2 <ip> for IPMI endpoints
• Kubernetes ClusterIPs don't respond to ICMP
• Results in "BMC is not listening" even when IPMI is reachable

Feature Description

Replace icmp ping with an ASF Presence Ping (RMCP UDP probe). This is the standard way to check IPMI reachability (IPMI v2.0 spec, section 13.2.3) and probes the actual IPMI service rather than relying on icmp

Describe your ideal solution

Proposed solution:

1. Send a 12-byte ASF Presence Ping packet to the IPMI UDP port
2. Wait for a Presence Pong response
3. Returns true if the IPMI endpoint responds

Describe any alternatives you have considered

No response
