atest host skylab_migrate command MVP
MVP functionality for `atest host skylab_migration` command.
`atest` post-this-CL is capable of migrating explicitly specified hosts and writes a JSON report of what it did to stdout, e.g.
```
{
"duts": {
"migrated": [
"chromeos1-row4-rack9-host2"
],
"needs_add_to_skylab": [],
"needs_drone": [],
"needs_rename": [],
"not_locked": []
},
"failed_step": null,
"locked_success": true,
"plan": {
"retain": [],
"transfer": [
"chromeos1-row4-rack9-host2"
]
}
}
```
That being said, I had to remove a couple of bugs in order to get it to work end to end... and all of those fixes are in this diff.
That's why the diff is relatively large.
Non-MVP functionality such as specifying boards and pools and models has a draft implementation here, but hasn't really been tested.
