In getThreadIDs(), the cpuID variable is derived from a string that
already contains a whitespace. As a result, strings.SplitAfter returns
the cpuID with a leading space. This makes any go variant of string to int
fail (strconv.ParseInt() in our case). This patch makes sure that the
leading space character is removed so the string passed to
strconv.ParseInt() is "CPUID" and not " CPUID".
This has been caused by a change in the naming scheme of vcpu threads
for Firecracker after v0.19.1.

The client code (and APIs) for Cloud Hypervisor has been changed
dramatically due to the upgrade to `openapi-generator` v5.2.1. This
patch migrate the Cloud Hypervisor driver in the kata-runtime to use
those updated APIs.
The main change from the client code is that it now uses "pointer" type
to represent "optional" attributes from the input openapi specification
file.

When running a firecracker instance jailed, block devices
are not removed correctly, as the jailerRoot path is not
stripped from the PATCH command sent to the FC API.
This patch differentiates the jailed case from the non-jailed
one and allows the firecracker instance to be properly
terminated.

Kata uses the 'kernel_irqchip' machine option to qemu. By default it
uses it in what qemu calls the "short-form boolean" with no parameter.
That style was deprecated by qemu between 5.2 and 6.0 (commit
ccd3b3b8112b) and effectively removed entirely between 6.0 and 6.1
(commit d8fb7d0969d5).
Update ourselves for newer qemus by using an explicit
"kernel_irqchip=on".

The cause of this issue is there are two elements store the resources
infomation. They are c.config.Resources for calculateSandboxMemory and
c.GetPatchedOCISpec() for agent.
This add initConfigResourcesMemory to Container and call it in
newContainer to handle the issue.

When enabling tracing with Cloud Hypervisor, we end up establishing 2
connections to 2 different HTTP servers: The Cloud Hypervisor API one
that runs over a UNIX socket and the Jaeger endpoint running over UDP.
Both connections use the default HTTP golang client instance, and thus
share the same transport layer. As the Cloud Hypervisor implementation
sets it up to be over a Unix socket, the jaeger uploader ends up going
through that transport as well, and sending its spans to the Cloud
Hypervisor API server.
We fix that by giving the Cloud Hypervisor implementation its own HTTP
client instance and we avoid sharing it with anything else in the shim.
