[KA02] internal cleanup and refactor for SocketKeepalive

In previous change, the new SocketKeepalive API was exported.
But internally, old PacketKeepalive names and structures are
still used.

This change rename them properly for code consistency and also
refactor KeepalivePacketData to support different types of
KeepalivePacketData.
