core: add internet connectivity check

* use libsoup to compare a http response from a given
  uri with a given response (use g_str_has_prefix () to compare)
* do periodically check the connectivity. Check interval is configurable
* check connectivity when device state change
  from/to NM_DEVICE_STATE_ACTIVATED
