The current network namespace parameter nested in the JailerConfig parameter requires specifying the entire jailer configuration, which is not convenient and doesn't allow using the noop jailer with a network namespace. To overcome this limitation, add a new NetNS parameter to the CreateVM request. See also a similar change in firecracker-microvm/firecracker-go-sdk#155.

In order to support firecracker snapshot-restore we need to make the following changes: * add a new CreateSnapshot request; * add new parameters for snapshot loading to the CreateVM request (following the firecracker Golang SDK design, snapshot loading is essentially creating a VM with additional snapshot options). When a VM is created by loading a snapshot, it's container snapshot drives are already mounted, so the drive mount stub creation and mounting is skipped. Also add a NetNS (network namespace) parameter to the CreateVM request, since the current NetNS parameter nested in the JailerConfig parameter requires specifying the entire jailer configuration, which is not convenient.
