The responsible of the client package is to transform a go struct into an HTTP request, perform the HTTP request, and convert the HTTP response into a go struct + error.

client/service_update.go and client/service_create.go have a bunch of application logic that does not belong in this package. We should remove it and move it into a separate package.

It looks like this logic was first introduced in #32388 and subsequently updated in #33239, and #33575.

This is related to #34242 and docker/cli#386
