Remove token-less agent support
Removes the deprecated support for token-less agents which
better secures the ironic-python-agent<->ironic interactions
to help ensure heartbeat operations are coming from the same
node which originally checked-in with the Ironic and that
commands coming to an agent are originating from the same
ironic deployment which the agent checked-in with to begin
with.
