Subscription Conformance Tests completion

[gabo1208]

Problem
We don't have all the MUST clauses in the Subscription spec covered by tests in the project, for example:
https://github.com/knative/eventing/blob/792f56ddb5e2328005149e7af571be6ca667cd89/test/rekt/features/channel/data_plane.go lots of todo in .must clauses in this file.
Same with the other CRDs (Subscription, Broker, Trigger)

Persona:
Developers

Exit Criteria
Have at least one test per MUST clause from the Subscription specs

Additional context (optional)
This is part of the Conformance GA plan

Who can add more details of this issue?
What kind of tests? Does it mean to add unit tests or validation tests?
What's MUST cause in subscription spec? It will be helpful to add a link to a "MUST cause" sample here.
Thanks.

@gabo1208 will you check if my PR satisfied your requeirments? If it is, I could provide more conformance tests.
