refactor: move shipping and surcharges from server/no-meteor to node-app

[kieckhafer]

Resolves #5620 & #5618
Impact: minor
Type: refactor

As part of our effort to separate our Reaction Admin from our Reaction Node API, we are moving our GraphQL services from their respective /imports/plugins/*/server/no-meteor/ folders into their new /node-app/{core-services|plugins}/* folder.

Updates also include future-proofing some existing code, including adding filetype extensions (and index.js to imports)

This PR moves both the shipping and surcharges packages, as surcharges relies on shipping.

Breaking changes

Any custom plugins that import files directly from the address package will need to be updated.

Testing

1. Start the application and see that it works as it should.
2. Test any GraphQL mutation that has been moved in this process, such as:

query {
  surchargeById(surchargeId: "SURCHARGE_ID", shopId: "SHOP_ID") {
    _id
    amount
  }
}

@aldeed there is a new query created here, so this is a bit more in depth than just moving files between packages, please double check the new getCommonOrderForCartGroup query, which replaces xformCartForCommonOrder.

[aldeed]

Sorry for not being clear. I don't think it's a good idea to have this query in GraphQL. It should be for internal use only. Maybe this would change at some point but for now CommonOrder is more of an internal concept among plugins that doesn't need to be part of the GraphQL schema.
