vmm: api: Add HTTP server

Browse Source 
The Cloud Hyper HTTP server runs a synchronous, multi-threaded
loop that receives HTTP requests and tries to call the corresponding
endpoint handlers for the requests URIs.

An endpoint handler will parse the HTTP request and potentially
translate it into and IPC request. The handler holds an notifier and an
mspc Sender for respectively notifying and sending the IPC payload to
the VMM API server. The handler then waits for an API server response
and translate it back into an HTTP response.
The HTTP server is responsible for sending the reponse back to the
caller.

The HTTP server uses a static routes hash table that maps URIs to
endpoint handlers.
