Vincent Demeester f0d277fe84
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).
