Disable license entitlement

[mproffitt]

What changed?

Why was this change made?

As Weave GitOps Enterprise has now moved to OpenSource, the entitlement validation no longer makes sense as it relies on closed source code that probably won't remain in the codebase.

This change disables the check by removing irrelevant parts of code and setting the license expiry to always be time.Now() + 1 year

How was this change implemented?

How did you validate the change?

• Explain how a reviewer can verify the change themselves

By deploying this branch on a license free cluster and verifying that the check no longer takes place

• Integration tests -- what is covered, what cannot be covered;
  or, explain why there are no new tests

This removes functionality and does not introduce any new functionality that requires coverage

• Unit tests -- what is covered, what cannot be covered; are
  there tests that fail without the change?

This removes tests that cover code that is no longer relevant

Release notes
