Feature Overview (aka. Goal Summary)  

With oc-mirror v2 becoming the default tool, we need to ensure we can safely remove v1 code base.

Goals (aka. expected user outcomes)

• Add a warning to the oc-mirror in 4.20 to say that v1 is deprecated and starting 4.21 it will be required to specify --v1 or --v2 when running the tool. There will be no default version in 4.21. 
• Add release note clarifying this 
• Check if possible to add a warning to the console download page about this as well.
