cd0208fe0a api-client: Allow response to be captured 
Previously, the API response was always written to stdout, but that may
not be appropriate for all clients.

The client can now control this behaviour as the client API returns the
response in the `Result`.

Fixes: #4703.

eea9bcea38 api-client: Refactor to removed hard-coded prefix 
The existing API client only allows access to "VM" operations, so added
a new `simple_api_full_command_with_fds()` that allows access to "VMM"
operations too.

Also added a `simple_api_full_command()` to avoid having to specify the
file descriptors, in a similar manner to `simple_api_command()`.

Fixes: #4701.

87c0791d53 api-client: Handle body_offset is None 
Handle the case `body_offset` is `None` instead of calling `unwrap()`
which leads to a panic.

686e6d5082 api-client: Break the receive loop if the VMM shuts down the socket 
Breaks the receive loop of the API client when the VMM shuts down the
socket connection. A shutdown is indicated by the return value 0 of the
`recv()` system call.[^1][^2] This case was not handled before, so the
API client tried infinitely to receive more bytes and did not return.

Split out the HTTP request handling code from ch-remote into a new
crate which can be used in other places where talking to the API server
by HTTP is necessary.
