[master] Revert "[master] tag initializing keys so they can't be used for normal validation"

Browse Source

This change created a potential race between key refresh queries and
root zone priming queries which could leave the root name servers in
the bad-server cache.

ns3 is a validator with a broken key in managed-keys.
ns4 is a validator with a deliberately broken managed-keys.bind and

Tests TODO:
ns5 is a validator which is prevented from getting a response from the
root server, causing key refresh queries to fail.
- initial working KSK
TODO: test using delv with new trusted key too
- introduce a REVOKE bit
- later remove a signature
- corrupt a signature
