* Always Close() the Worker instance
* orchard list vms: show assigned worker for each of the VMs
* Stop the failed VMs before we schedule new VMs
To avoid violating resource constraints.
* syncOnDiskVMs: don't ignore running VMs
* Worker: show correct remote and local VM counts
* Implement restart policy for VMs
* Do not update VM.Resource, we only use it as a read-only specification
* Err()/setErr(): use atomic.Pointer instead of sync.Mutex
* Fail VMs if the worker had crashed/is unhealthy
* OnDiskName: properly handle cases when VM's name contains hyphens
* Worker: introduce Offline() method and check it before scheduling
* tart.List(): use Tart's JSON output
* OnDiskName: remove empty parts check
* Scheduler: move health-checking logic to a separate function
* Only fail "running" VMs
* Only fail orphaned VMs if they're in terminal state
* Integration tests
* Run healthCheckingLoopIteration() before schedulingLoopIteration()
* Worker: sync on-disk VMs only once at start
Before we had two main loops: controller loop to assign VMs and worker loop to start VMs. Each of the loops was performed upon an interval every N seconds.
This change introduces a mechanism for reactively requesting loop execution:
1. Controller loop will be executed upon VM creation to try to immediately schedule.
2. A worker will be notified upon a VM assigment and worker loop will be requested to sync immediately.
Fixes#31
* Resources support
* Ability to provide VM and worker resources via the CLI

* OpenAPI: document "resources" field
* orchard dev: serve Swagger API documentation on /v1/
* Integration guide
* proxy.Connections(): handle "use of closed network connection" error
* Controller: less strict timeouts that work nicely for WebSockets

* Implement Proxy cancellation
* Use Protocol Buffers structure directly in Watcher
* Fix TestWatcher after switching to Protocol Buffers structure
