feat(bin): disable ETA for execution stage

[shekhirin]

We receive a lot of reports from users who are confused about the ETA for Execution stage, e.g.:

For example, I'm on stage 5 (execution) and have seen the eta be anywhere from 6 hours to 31 days.

The problem is that our ETA works only on two points (previous and current timestamps), and the progress for Execution stage is measured in gas, which is likely not an ideal proxy for real CPU time.

For the time being, I think we should disable the ETA reporting for Execution stage completely, and leave just the percentage progress which should be enough to get the idea of how long it takes to complete.

reasonable,

can we track readding this once we thought about this a bit more?
