59339feac3 jsonrpc: tolerate null json value for parameters in json-rpc call
Rust lang has notion of empty value `()` which is translated to json null
value using serialization library like serde. Thus it means that jsonrpc
methods having no parameters translate to parameters with null value (as
opposed to a request without parameter member as it is done now in spdk).
This change handles null parameter gracefully instead of returning an
error - improving interoperability with such clients.

7d38f16674 jsonrpc client: non-blocking mode
This patch enables non blocking mode in RPC client. Requests are send
and received during spdk_jsonrpc_client_poll.

e6c30818e3 test: don't use bdev_svc application in this test
bdev_svc require system setup (like bdevs, nvme etc.) otherwise it
writes tons of  errors. Instead just start RPC server on separate thread
and connect to it.

2f557958d0 jsonrpc: add internal poll handler
As preparation for non blocking mode make the
spdk_jsonrpc_client_send_request functon just queue the request. Then in
spdk_jsonrpc_client_recv_response we actually send it. Without this
change send function will stay blocking.

5d0f262073 jsonrpc: introduce spdk_jsonrpc_client_response
As a step toward non-blocking JSON RPC client change the the way we
retrive the response.

Now we retrive full response by calling
spdk_jsonrpc_client_recv_response(). If response is ready it will be
parsed to spdk_jsonrpc_client_response object then user can issue
spdk_jsonrpc_client_get_response() to get the response object. When
processing response object is done the user calls
spdk_jsonrpc_client_free_response() to free it.

This logic will simplify both non-blocking mode and multiple response
handling.

8397285b50 jsonrpc_client: make ID and method optional when starting request
In JSON RPC the ID is optional. Method is mandatory but user might want
to produce the name later or by using
spdk_json_write_named_string_fmt(). This patch also changes the argument
order.
