Add -failfast option to let test exit on error, but -failfast option
can't cross package, so there is a for loop used to test on all packages
in src/runtime, and the parallel number is set to 1, this may lead test
to be slow.

very confused. So this pr sync the codes to api documents.

Current handling of read-only mounts is a little tricky.
However, a clearer solution can be used here:
1. make a private ro bind mount at privateDest to the mount source
2. make a bind mount at mountDest to the mount created in step 1
3. umount the private bind mount created in step 1
One important aspect is that the mount in step 2 is duplicated from
the one we created in step 1. So the MS_RDONLY flag is properly
preserved in all mounts created in the propagtion.

The kata-agent supports seccomp feature based on the OCI runtime specification.
This seccomp capability in the kata-agent is enabled by default.
However, it is not enforced by default: users need to enable that by setting
`disable_guest_seccomp` to `false` in the main configuration file.

On a conventional (e.g. runc) container, passing in a VFIO group device,
/dev/vfio/NN, will result in the same VFIO group device being available
within the container.
With Kata, however, the VFIO device will be bound to the guest kernel's
driver (if it has one), possibly appearing as some other device (or a
network interface) within the guest.
This add a new `vfio_mode` option to alter this. If set to "vfio" it will
instruct the agent to remap VFIO devices to the VFIO driver within the
guest as well, meaning they will appear as VFIO devices within the
container.
Unlike a runc container, the VFIO devices will have different names to the
host, since the names correspond to the IOMMU groups of the guest and those
can't be remapped with namespaces.
For now we keep 'guest-kernel' as the value in the default configuration
files, to maintain current Kata behaviour. In future we should change this
to 'vfio' as the default. That will make Kata's default behaviour more
closely resemble OCI specified behaviour.

Currently constrainGRPCSpec always removes VFIO devices from the OCI
container spec which will be used for the inner container. For
upcoming support for VFIO devices in DPDK usecases we'll need to not
do that.
As a preliminary to that, add an extra parameter to the function to
control whether or not it will remove the VFIO devices from the spec.

In order to support DPDK workloads, we need to change the way VFIO devices
will be handled in Kata containers. However, the current method, although
it is not remotely OCI compliant has real uses. Therefore, introduce a new
runtime configuration field "vfio_mode" to control how VFIO devices will be
presented to the container.
We also add a new sandbox annotation -
io.katacontainers.config.runtime.vfio_mode - to override this on a
per-sandbox basis.
For now, the only allowed value is "guest-kernel" which refers to the
current behaviour where VFIO devices added to the container will be bound
to whatever driver in the VM kernel claims them.

The current kernel version parse lib can't process suffix '+', as the
modified kernel version will add '+' as suffix, thus panic will occur.
For example, if the current kernel version is "5.14.0-rc4+", test
TestHostNetworkingRequested will panic:
--- FAIL: TestHostNetworkingRequested (0.00s)
panic: &{DistroName:ubuntu DistroVersion:18.04
KernelVersion:5.11.0-rc3+ Issue: Passed:[] Failed:[] Debug:true
ActualEUID:0}: failed to check test constraints: error: Build meta data
is empty
Here, remove the suffix '+' in kernel version fix helper.

This PR includes these optimize changes:
- Remove the dependency on the container engine.
The old code uses runc to generate config.json and
Docker to export rootfs, that will be heavy and need
additional dependency.
Using a fixed config for busybox image can avoid
the heavy processing above.
- Moved duplicate code to pkg/katatestutils package

When running the TestIoCopy test, on some occasions, the test
runs too quick, and closes the stdin pipe before the ioCopy()
routine start to read from it. This causes a SIGSEGV error.
To fix this issue, I am adding additional read/write tests before
closing the pipes. As the read operation waits for the writer to
be done, this actually synchronizes the threads and make sure
the final tests (with closed pipes) works as expected.
