* Ability to set VM's power state and retrieve backing Tart VM's name
* Validate user-provided "powerState" field
* Introduce TestSpecUpdatePowerStateSuspend
* Introduce TestSpecUpdatePowerStateStopped
* OpenAPI specification: add note about suspended VMs to "tartName" desc.
* Sometimes we need to wait more than 30 seconds
* Simplify state reconciliation and support changing Softnet settings
* Remove unused "updateFunc" parameter from syncOnDiskVMs()
* Don't take an address of a loop variable
* ensure → ensures
* updateVMState(): don't forget to update VMState
* Introduce TestSpecUpdateSoftnet integration test
* Update OpenAPI specification to include generation/observedGeneration
* API: introduce ability to watch a VM
* Document ?watch=true for GET /vms/{name} in the OpenAPI specification
* WatchVM: ensure that goroutine is terminated on early return with error
* WatchVM: close channels on goroutine exit
* WatchVM: ensure that we wait for the goroutine after additional barriers
* WatchVM: ignore unexpected keys instead of throwing an error
* WatchVM: perform context-aware writes to a bounded channel
* WatchVM: don't forget to close errCh on goroutine exit too
* WatchVM: don't close readyCh in goroutine to avoid ambiguity
* WatchVM: filter out spurious KVs that signify VM deletion
* Allow creating VMs with implicit CPU and memory
* Clarify why cpu/memory can be 0 a bit better
* Controller(API): don't forget to update DefaultCPU and DefaultMemory
* Add an integration test for implicit CPU and memory
* Controller: emit lifecycle events when the VM gets restarted or deleted
* vm_{scheduling,run}_time → vm_{scheduling,run}_duration for clarity
* Update VM endpoint: only update VM started time when zero
* 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
* Controller API: introduce controller's information endpoint
* Prevent generation of empty events after channel closure
* Allow events to be buffered in the events channel
* Controller API: introduce controller's information endpoint[1]
* IntegrationGuide.md: a couple of Python and Golang examples
* Rephrase a sentence

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
* orchard dev: always listen on :6120
* orchard dev: support --resources
* REST API: provide resource defaults when creating VM
* OpenAPI: document "resources" field
* orchard dev: serve Swagger API documentation on /v1/
* Integration guide
* Generic Events
We can try to use these generic events for script execution and storing of the output logs in events with `log` kind.
* Lint issues
* Cleanup events upon VM deletion
* Basic integration test
* Run an actual VM in tests
* Apply suggestions from code review
