While sending API requests that don't need any body, explicitly set
CURLOPT_INFILESIZE to 0.
Without this option, curl sends a chunked request with `Expect: 100-continue`
header. The client, in this case curl, expects a response from the server,
ch in this case, to respond within a timeout period.
If guest definition has a PCI passthrough device configuration,
cloud-hypervisor process cannot respond within above mentioned timeout.
Even if cloud-hypervisor responds after the timeout, curl cannot read
the response. Because of this, virsh request to create a guest, hangs. This
only happens while using "mshv" hypervisor.
By setting CURLOPT_INFILESIZE to O, curl drops the Expect header and
sychronously waits for server to respond.
