First PR to address #14244. Adds common potential reasons as to why a direct connection to the workspace agent couldn't be established to `coder ping`: - If the Coder deployment administrator has blocked direction connections (`CODER_BLOCK_DIRECT`). - If the client has no STUN servers within it's DERP map. - If the client or agent appears to be behind a hard NAT, as per Tailscale `netInfo.MappingVariesByDestIP` Also adds a warning if the client or agent has a network interface below the 'safe' MTU for tailnet. This warning is always displayed at the end of a `coder ping`.
