03398532dc ci: Bump to kernel 5.6-rc4
The kernel version is updated from 5.5-rc1 to 5.6-rc4, including the
updated kernel config file.

The kernel branch contains virtio-fs, virtio-iommu and virtio-mem
patches that are not upstream yet. It also contains one fix for
virtio-vsock which will be merged upstream in the next release.

77ee331be0 resources: Enable KASLR in kernel config
This option improves the security of the guest by randomising the start
address of the kernel in physical memory. We should turn this on so as
to ensure all our functionality such as memory hotplug and kernel
loading works as this is an option used widely in production.

db6f894e5e scripts: Add container based development script
The script is a development tool that runs all commands in a dedicated
container. This allows for containerized, isolated and reproducible
builds and CI runs.

The script supports the following command:

* build: Build Cloud Hypervisor binaries (debug and release)
* build-container: Build the container used by the script
* tests: Run unit, cargo and integration tests

$ ./scripts/dev_cli.sh help

Cloud Hypervisor dev_cli.sh
Usage: dev_cli.sh <command> [<command args>]

Available commands:

    build [--debug|--release] [-- [<cargo args>]]
        Build the Cloud Hypervisor binaries.
        --debug               Build the debug binaries. This is the default.
        --release             Build the release binaries.

    tests [--unit|--cargo|--all]
        Run the Cloud Hypervisor tests.
        --unit               Run the unit tests.
        --cargo              Run the cargo tests.
	--integration        Run the integration tests.
        --all                Run all tests.

    build-container [--type]
        Build the Cloud Hypervisor container.
        --dev                Build dev container. This is the default.

aa4efdd7ec ci: Update kernel related to virtio-iommu
Because of the new set of patches related to virtio-iommu allowing only
for the topology to be described through virtio configuration, this
patch updates the kernel branch and the kernel configuration our CI
relies on.

eff78f746a resources: Prevent kernel config interactive shell from showing up
Following the recent addition of CONFIG_EXPERT=y, the kernel config now
asks for several options through interactive shell. This is not
convenient when locally running the integration tests script as the
shell asks for input.

cb59f826ad scripts: Use virtio-fs-virtio-iommu branch as custom kernel

custom kernel is now based on the kernel branch virtio-fs-virtio-iommu.

688ec0eb2d resources: Update kernel config
In order to support nested virtualization and nested device passthrough
from our CI tests, we need some extra kernel configuration options to be
enabled.

CONFIG_KVM and CONFIG_VIRTUALIZATION for nested virtualization.
CONFIG_VFIO for nested device passthrough.
CONFIG_VIRTIO_IOMMU and CONFIG_ACPI_IORT for virtio-iommu support.

With all these new options applied, we can leverage virtio-iommu to
attach some VFIO devices to it and pass them through a second layer of
virtualization.

af9a72eab6 tests: Add virtio-fs tests with dax=on and dax=off
The existing integration tests are extended to support both use cases
where dax=on and dax=off.

In order to support DAX, the kernel configuration needs to be updated to
include CONFIG_FS_DAX and CONFIG_ZONE_DEVICE.

021e8d9e13 tests: Move to new kernel 5.3-rc3
The last kernel we were using included some manual porting of the
virtio-pmem and virtio-fs patches. By moving to 5.3-rc3, we are now
closer to upstream since the virtio-pmem patches are part of the linux
kernel now. Additionally, this includes the latest patches from
virtio-fs maintainers, which works with the latest version of virtiofsd.

0fcca3ed74 tests: Add virtio-fs testing
This commit introduces the testing of the --fs option based on the
virtio-fs implementation. This does not simply add a test, but also
updates the integration script by generating a new kernel embedding
the virtio-fs patches and by downloading the virtiofsd daemon.
