remote checkpoint/restore: more fixes

* Support `checkpoint --pre-checkpoint`

* Support `checkpoint --with-previous`

* Disable `restore --import-previous` for the remote client since we had
  to send two files which in turn would require to tar them up and hence
  be a breaking change.  Podman 4.0 would be the chance and I hope we'll
  find time before that to remote-restore prettier.

Note that I did not run over swagger yet to check whether all parameters
are actually documented due to time constraints.

Fixes: #12334
