Jose Carlos Venegas Munoz 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
