CompatOCISpec: limit usage of CompatOCISpec
Browse files Browse the repository at this point in the history 
Fixes: #2023

CompatOCISpec is used to gurantee backward compatbility for old runtime
specs, after we convert CompatOCISpec to standard specs.Spec, we should
use specs.Spec instead of CompatOCISpec, and CompatOCISpec should be
useless from then.

Spread usage of CompatOCISpec can make code structure confusing and making
the runtime spec usage non-standard. Besides, this can be the very first
step of removing CompatOCISpec from config's Annotations field.
