change: Support hiding specific progress bars in summary mode

[upbqdn]

We could support hiding the progress bars that users don't find interesting. For example, as a user, I feel like the "Checkpoint Queue Height" doesn't bring much new info compared to other progress bars.

Here's one possible design:

• the progress bars config gets passed to every service/task that has progress bars
• based on that config, some progress bars decide to hide themselves in summary mode
