* Load testing: synthetic VMs, multiple worker support and Grafana k6 test
* echoserver: prevent fallthrough when Accept() fails
* Move default local-dev context logic to CreateDevController()
* Synthetic: add a random delay to startup script echoing
* 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
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.
