Description

We have places in the FE/BE where we use INFO when it should be VLOG(1) or lower.

If we change all them, (there aren't too many), so that the INFO messages are service wide things, then we can change the logging defaults so that INFO is flushed and VLOG is buffered.

The service wide messages are often critical to see and should be very infrequent.
