Remove support for runc only #375
Description
Current behavior
Currently, we have many modes to run guardian. This issue is meant to deprecate runc mode. We are currently testing for this mode, but the addition of this mode is slowing down our process to release garden-runc-release. By default containerd mode is the default and recommended. Please comment below if you are still using runc mode and if there are hurdles to move to containerd mode.
Desired behavior
Remove support for runc mode in pipelines for gats and guardian.
Affected Version
