feat(rust): add support for "launch-configuration" in node's config

[adrianbenavides]

Adds support to pass the launch-configuration (now renamed to services) as part of the node configuration:

ockam node create '{
  name: n1,
  tcp-listener-address: "127.0.0.1:14001",
  start-default-services: true,
  services: {
    control-api: {
      authentication-token: token,
      backend: true,
      frontend: true,
      http-bind-address: "127.0.0.1:14002",
      node-resolution: relay
  }}}'
