Cleanup: merge container-related jobs into daemon/

This is part of the effort to remove the deprecated `server` package. The job interface is unchanged.

The following jobs are moved out of `server/` and into `daemon/`:

```
"attach":            daemon.ContainerAttach,
"commit":            daemon.ContainerCommit,
"container_changes": daemon.ContainerChanges,
"container_copy":    daemon.ContainerCopy,
"container_inspect": daemon.ContainerInspect,
"containers":        daemon.Containers,
"create":            daemon.ContainerCreate,
"delete":            daemon.ContainerDestroy,
"export":            daemon.ContainerExport,
"kill":              daemon.ContainerKill,
"logs":              daemon.ContainerLogs,
"pause":             daemon.ContainerPause,
"resize":            daemon.ContainerResize,
"restart":           daemon.ContainerRestart,
"start":             daemon.ContainerStart,
"stop":              daemon.ContainerStop,
"top":               daemon.ContainerTop,
"unpause":           daemon.ContainerUnpause,
"wait":              daemon.ContainerWait,
```
