Getting ETA for model training

[rajatscibi]

Describe the workflow you want to enable

Getting an estimate time for a model to train or an estimated time remaining before the training is completed.

Describe your proposed solution

Understand computational resources to get an estimate on time to train. OR
Use the already elapsed time to computed estimated time remaining. For example. if 10% training gets completed in 60 sec, ETA for 100% becomes 600 sec or similar.

Describe alternatives you've considered, if relevant

Tried scitime but thats a very invasive method. Would prefer a method that is more tightly coupled with sklearn functionality.

This is a recurrent feature request that will be resolved by the ongoing work on a callback API (#22000)

I'm closing this issue because it is a duplicate of #10973 and #78.
