wgengine/magicsock: add client flag and envknob to disable heartbeat ( #5638 )
...
Baby steps towards turning off heartbeat pings entirely as per #540 .
This doesn't change any current magicsock functionality and requires additional
changes to send/disco paths before the flag can be turned on.
Updates #540
