Move integration-cli daemon package to internal/test…
… and do not use the `docker` cli in it. One of the reason of this move is to not make `integration` package using legacy `integration-cli` package. Next move will be to support swarm within this package *and* provide some helper function using the api (compared to the one using cli in `integration-cli/daemon` package).
