For example, under debian buster/sid. Those information should be
provide with best effort instead of error out. Set name and version
to "<<unknown>>" if they are not defined.

There is no vendor field in /proc/cpuinfo contents
on ppc64le. Make sure to return "" for vendor field
for ppc64le and fix all the corresponding testcases
as well.

Add host cgroup support for kata.
This commits only adds cpu.cfs_period and cpu.cfs_quota support.
It will create 3-level hierarchy, take "cpu" cgroup as an example:
```
/sys/fs/cgroup
|---cpu
|---kata
|---<sandbox-id>
|--vcpu
|---<sandbox-id>
```
* `vc` cgroup is common parent for all kata-container sandbox, it won't be removed
after sandbox removed. This cgroup has no limitation.
* `<sandbox-id>` cgroup is the layer for each sandbox, it contains all other qemu
threads except for vcpu threads. In future, we can consider putting all shim
processes and proxy process here. This cgroup has no limitation yet.
* `vcpu` cgroup contains vcpu threads from qemu. Currently cpu quota and period
constraint applies to this cgroup.

Add a heuristic to ensure the amount of memory allocated to the
hypervisor is bigger than the size of the image.
This catches simple configuration issues where `default_memory=` is set
to a smaller value than the size of either the `image=` or `initrd=`
files.
If the configured image type is `initrd`, fail but only warn in the
logs for `image` as although it seems a highly unlikely scenario, it is
permitted.
Update tests to ensure that created resources have `>0` bytes.
Fixes#636.

Ephemeral volumes should not be passed at 9pfs mounts.
They should be created inside the VM.
This patch disables ephemeral volumes from getting
mounted as 9pfs from the host and instead a corresponding
tmpfs is created inside the VM.

The CPUinfo need to be refined in Arm architecture, because the
vendor and model of CPU may refer to different meaning in Arm architecture.
Besides, relevant contents extracted from /proc/cpuinfo may need to be
normalized for human-readability.

Many cli and arch files were using the 'older style' fairly full
Apache license text. The project standard is the shorter SPDX style.
Convert them over.
