Remove obsolete protocol policies from policy.v3cloudsample.json

[Lance Bragstad]

Once support for scope types landed in the protocol API policies, the policies in policy.v3cloudsample.json became obsolete [0][1].

We should add formal protection for the policies with enforce_scope = True in keystone.tests.unit.protection.v3 and remove the old policies from the v3 sample policy file.

This will reduce confusion by having a true default policy for protocols.

    Remove protocol policies from v3cloudsample.json

    By incorporating system-scope and default roles, we've effectively
    made these policies obsolete. We can simplify what we maintain and
    provide a more consistent, unified view of default protocol
    behavior by removing them.
