daeab40b45 os.Unmount: do not consult mountinfo, drop flags 
1. Currently, Unmount() call takes a burden to parse the whole nine yards
of /proc/self/mountinfo to figure out whether the given mount point is
mounted or not (and returns an error in case parsing fails somehow).

Instead, let's just call umount() and ignore EINVAL, which results
in the same behavior, but much better performance.

This also introduces a slight change: in case target does not exist,
the appropriate error (ENOENT) is returned -- document that.

2. As Unmount() is always used with MNT_DETACH flag, let's drop the
flags argument. This way, the only reason of EINVAL returned from
umount(2) can only be "target is not mounted".

3. While at it, remove the 'containerdmount' alias from the package.

ca16bd601a runtime: Add trusted runtime option 
Some CRI compatible runtimes may not support provileged operations.
Specifically hypervisor based runtimes (like kata-containers, cc-runtime
and runv) do not support privileged operations like:

- Provide access to the host namespaces
- Create fully privileged containers with access to host devices

Hypervisor based runtimes create container workloads within virtual machines.
When a running host privileged containers using them,
they wont provide support to requested the privileged opertations.

This commits add the new options to define two runtimes:

Trusted runtime : Used when a privileged container is requested.
Default runtime : for non-privileged workloads.

A container that belongs to a privileged pod will inherent this property
an will be created with the trusted runtime.

- Add options to define trusted runtime
- Add logic to decide if a sanbox is trusted
- Export annotation containers below to a trusted sandbox

b383b0261a Annotations: Provide container metadata for VM based runtimes 
For hypervisor-based container runtimes (like Kata Containers, Clear Containers
or runv) a pod will be created in a VM and then create containers within the VM.

When a runtime is requested for container commands like create and start, both
the instal "pause" container and next containers need to be added to the pod
namespace (same VM).

A runtime does not know if it needs to create/start a VM or if it needs to add a
container to an already running VM pod.

This patch adds a way to provide this information through container annotations.
When starting a container or a sandbox, 2 annotations are added:

- type (Container or Sandbox)
- sandbox name

This allow to a VM based runtime to decide if they need to create a pod VM or
container within the VM pod.

0161764ef5 Always use a writeable snapshot as the rootfs. 
This will be made readonly by runc based on spec.Root.Readonly (which we
already set correctly) but defering until then gives runc the chance to make
any missing mount points as it processes the spec.Mount array.

This is necessary because many container images lack mount points for things
like the /etc/hosts which we want to overbind. This is not noticed with e.g.
Docker because it automatically creates an additional layer containing those.
This is something we may want to do here as well eventually but for now using a
writeable snapshot is both necessary and sufficient.

The same does not apply to the sandbox since we never modify its rootfs or want
to mount anything in it etc, add a comment to clarify.

Fixes #220.
