feat: netlink queueNum/table config options

[kpetku]

OpenGFW currently hard codes the netlink table name and queue number which causes conflict errors such as could not bind to requested queue 100: netlink receive: operation not permitted when running multiple instances of the application on the same host using different rulesets.

This pull request exposes configuration options that allow the user to set a unique table name and queueNum if they want to run multiple instances, for example:

io:
  queueSize: 1024
  table: 'opengfw2' # use a unique table if you want to run multiple instances
  queueNum: 102 # use a unique queue if you want to run multiple instances
  local: true # set to false if you want to run OpenGFW on FORWARD chain

Setting a unique table name will help prevent one instance from removing another already running application's rules when it exits.
