Description

Right now logging in the convergence sampling mode is almost useless. The @logprogress requires passing a fraction from 0 to 1, which isn't conducive to convergence logging at all. I realize this is backed up into the design of ProgressLogging.jl, which is even further backed up into the current logging backends, some parts end up tied directly into base julia. I've tried circumventing the issue by printing out my own statements but they actually get gobbled up due to the @withprogresslogging context.

I'm not sure the best path forward, other than re-introducing the ProgressMeter.jl dependency only for those sampling routines.

Research direction

Start by reading the convergence sampling routines and the ProgressLogging.jl design around @logprogress and @withprogresslogging. Compare their behavior with the current logging backends and the suggested ProgressMeter.jl dependency. Done means convergence sampling reports useful progress without messages being swallowed, with the chosen design agreed for the affected logging paths.
