This commit ensures that the HttpApi thread flushes all the responses before the application shuts down. Without this step, in case of a VmmShutdown request the application might terminate before the thread sends a response.

Describe the bug
When cloud-hypervisor receives a vmm.shutdown request it doesn't wait until the reply for it is actually flushed by the HTTP worker thread.
To Reproduce
Start many (40+) cloud-hypervisor processes in parallel and send each a vmm.shutdown request.
