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.

This commit add option "enable_guest_swap" to config hypervisor.qemu.
It will enable swap in the guest. Default false.
When enable_guest_swap is enabled, insert a raw file to the guest as the
swap device if the swappiness of a container (set by annotation
"io.katacontainers.container.resource.swappiness") is bigger than 0.
The size of the swap device should be
swap_in_bytes (set by annotation
"io.katacontainers.container.resource.swap_in_bytes") - memory_limit_in_bytes.
If swap_in_bytes is not set, the size should be memory_limit_in_bytes.
If swap_in_bytes and memory_limit_in_bytes is not set, the size should be
default_memory.

For some reason our static check started to get opinionated about code
that's been there for ages.
One of the suggestions is to improve:
```

client.go:431:2: S1017: should replace this `if` statement with an unconditional `strings.TrimPrefix` (gosimple)

First of all, cpuset.go just comes from kubernetes and we shouldn't be
doing much with this file apart from updating it every now and then
(but that's material for another PR).
Right now, due to some change on the static checks we use as part of our
CI, we started getting issues as:
```
INFO: Running golangci-lint on /home/fidencio/go/src/github.com/kata-containers/kata-containers/src/runtime/virtcontainers/pkg/cpuset
cpuset.go:60:2: SA4005: ineffective assignment to field Builder.done (staticcheck)
b.done = true
```
For those, let's just ignore the lint and move on.
