vmm: {De}serialize VmConfig

Browse Source 
We use the serde crate to serialize and deserialize the VmVConfig
structure. This structure will be passed from the HTTP API caller as a
JSON payload and we need to deserialize it into a VmConfig.

For a convenient use of the HTTP API, we also provide Default traits
implementations for some of the VmConfig fields (vCPUs, memory, etc...).
