[feature] allow manual gateway selection for vpn

For now, the way to select a gateway is to add a section in
bitmaskd.cfg:

  [vpn_prefs]
  locations = ["frankfurt", "seattle__wa"]
  countries = ["DE", "US"]

Note that the location indication has priority over country code.

This will be exposed by the UI in release 0.11
