feat(actions): Isolate action

What is the purpose of this PR / why it is needed?

list of allowed IP addresses specified in the action parameter. For example, the below snippet defines an isolate action, that will block all incoming/outbound network traffic except for the 172.17.0.4 and 8.8.8.8 IP addresses, both remote and local destinations.

action:
- name: isolate
  whitelist:
    - 172.17.0.4
    - 8.8.8.8
