feat(node): carry connections on several cores

connection_processes (default 1) starts that many processes for the
WebRTC stack; sessions and keys stay in the node. Set from node.toml
or the Node page, applied to new connections.

+The Node page offers `connection_processes`, bounded by the machine's cores.

+The node refuses a number above its core count, so a field that let one be
+typed would be a field whose Save fails. The ceiling comes with the settings
+(`cpu_count`, which the node adds and ignores when it is sent back).
