Include finalization, head and time (in that order) in standard bar (#1142) 

These are the 3 most important things in the life of a beacon-node -
finalization checkpoint for security, head + time for seeing that we're
synced and working.

The order given is the expected increasing order that things should be
moving in - finalization lags head, and head lags clock - the structure
helps the user remember, but also see the pattern where time is getting
out of sync with head.

A validator would also want to know when the next action is going to be
(ie next attestation / block production) but that's for another day.
