Add a socket and vhost_user parameter to this option so that the same
configuration option can be used for both virtio-net and vhost-user-net.
For now it is necessary to specify both vhost_user and socket parameters
as auto activation is not yet implemented. The original command line
parameter is still supported for now.

The number of queues and the size of each queue were not configurable.
In anticipation for adding multiqueue support, this commit introduces
some new parameters to let the user decide about the number of queues
and the queue size.
Note that the default values for each of these parameters are identical
to the default values used for vhost-user-blk, that is 1 for the number
of queues and 128 for the queue size.

The FsConfig structure has been recently adjusted so that the default
value matches between OpenAPI and CLI. Unfortunately, with the current
description, there is no way from the OpenAPI to describe a cache_size
value "None", so that DAX does not get enabled. Usually, using a Rust
"Option" works because the default value is None. But in this case, the
default value is Some(8G), which means we cannot describe a None.
This commit tackles the problem, introducing an explicit parameter
"dax", and leaving "cache_size" as a simple u64 integer.
This way, the default value is dax=true and cache_size=8G, but it lets
the opportunity to disable DAX entirely with dax=false, which will
simply ignore the cache_size value.

num_queues is set to 1, queue_size is set to 1024, and cache_size is set

When consumer of the HTTP API try to interact with cloud-hypervisor,
they have to provide the equivalent of the config structure related to
each component they need. Problem is, the Rust enum type "Option" cannot
be obtained from the OpenAPI YAML definition.
This patch intends to fix this inconsistency between what is possible
through the CLI and what's possible through the HTTP API by using simple
types bool and int64 instead of Option<u64>.
