It closes #8918

I'm still trying to ramp back up on this code b/c it is quite complex, but there are some things not working end-to-end, for example:

$ ipfs swarm limit svc:dht
{
  "Conns": 0,
  "ConnsInbound": 0,
  "ConnsOutbound": 0,
  "FD": 0,
  "Memory": 1115947008,
  "Streams": 32768,
  "StreamsInbound": 8192,
  "StreamsOutbound": 32768
}
$ ipfs swarm limit svc:dht --reset
{
  "Conns": 0,
  "ConnsInbound": 0,
  "ConnsOutbound": 0,
  "FD": 0,
  "Memory": 0,
  "Streams": 0,
  "StreamsInbound": 0,
  "StreamsOutbound": 0
}
$ ipfs swarm limit svc:dht
{
  "Conns": 0,
  "ConnsInbound": 0,
  "ConnsOutbound": 0,
  "FD": 0,
  "Memory": 0,
  "Streams": 0,
  "StreamsInbound": 0,
  "StreamsOutbound": 0
}

Yeah, I didn't fully understand the logic with default values here, so I was resetting to zero values as a default (that is how it works with unset values if you set a specific limit, all other values will be zero values).
